Polymeric films which can be used in packaging industries were prepared by blown film method with polypropylene chips and silver nanoparticles. The nanocomposite films were characterized concerning its potential use. Oxygen Transmission rate (OTR) measurements was done in order to ascertain permeability of oxygen through the polymeric films. It was found that the permeability of oxygen through nanocomposite film is higher than that of virgin polypropylene film due to incompatibility between polypropylene matrix and silver nanoparticles. The water vapour transmission rate (WVTR) test of the polymeric nanocomposite films was calculated in order to know the information about mass transfer mechanisms and solute-polymer interactions in the food packaging film. It has been found that, there is a significant decreased water vapour transmission rate through nanocomposite films compared to that of virgin polypropylene film. With increasing the concentration of silver nanoparticles, this effect was reduced. The explanation for this could be that with higher concentration of silver nanoparticles agglomeration in the polymer film could the possibility which create narrow pathway for water molecules to travel. The effect of various silver nanoparticles content in the polymer nanocomposites with respect to its antimicrobial efficacy against the Gram positive bacteria Escherichia coli and Gram positive bacteria Staphylococcus aureus were studied. However, Escherichia coli was most effectively retarded by silver nanoparticles than Staphylococcus aureus, which is related to the difference in the cell wall of the gram positive and gram negative bacteria.

The preservation of mould-ripened salami was investigated during 48 days at 19-20 °C under different packaging conditions: (i) high barrier film filled with air, 100 % N2 or under vacuum, (ii) biaxially oriented polypropylene film, (iii) microperforated polyethylene film and (iv) unpackaged. Sensory, texture profile, physicochemical and microbiological analyses were performed. Fungal quantification revealed two data groups. In group 1 (consisting of salami in microperforated polyethylene film, biaxially oriented polypropylene film and unpackaged) the conidium viability was relatively constant. In group 2 (salami preserved in high barrier film filled with air, 100 % N2 or under vacuum) the conidium viability decreased due to the absence of oxygen and the high carbon dioxide volume fraction. SEM micrographs showed micromorphological changes in fungal structure; microperforated polyethylene film, biaxially oriented polypropylene film and unpackaged conditions preserved the conidial morphology, while high barrier film filled with air, 100 % N2 or vacuum conditions collapsed the hyphae and most of the conidia. Salami packed in microperforated polyethylene film and biaxially oriented polypropylene film showed the most acceptable organoleptic characteristics and lower hardness and chewiness values after packaging.

Metallised polypropylene (MPP) capacitors, the dominant capacitor type used in a wide range of power and electronic circuit applications, offer high volumetric capacitor density, low cost, excellent frequency characteristics and a unique ability to recover from point failures in the dielectric film. However MPP capacitors have a generic weakness that is not well understood, failure of the self-healing process leading to ongoing catastrophic failure. The work described in this thesis includes the derivation of an improved electrical model of a capacitor and the uncovering of a mechanism for the catastrophic failure mode. Corrosion of the thin metallic field is firmly linked to drastic increases in metal film current densities and generation of hot spots in capacitors. In the work, novel formulae were derived relating capacitor parameters such as equivalent series resistance and equivalent series capacitance to frequency and physical characteristics such as metal film resistivity and physical dimensions of multiple layer capacitors. Modelling using numerical methods and diffusion equation showed that capacitors with double-end connection topology have more uniform voltage and power distribution than single-end connected capacitors. External characteristics of both connection topologies were shown to be virtually identical up to frequencies well above typical self-resonance. The aggregate spatial distribution of power from both layers and the voltage across the dielectric were found to be fundamentally different in the two circuit connection topologies. In this work it was shown that above singularity frequencies defined by distributed capacitance and metal film spreading resistance, equivalent series resistance and capacitance both fall with the square root of frequency Analysis of the inductance of typical MPP capacitors for single-end and double-end connected topologies and for circumferentially connected capacitor metallization showed that the magnitude and effect of distributed inductance in typical MPP power capacitors was insignificant compared to packaging inductance. Thermal and electrical modelling and experimental measurements showed that corrosion effects could readily account for the generic catastrophic failure mode of metallised polypropylene capacitors. Modelling showed that remnant vestiges of metal bridging corrosion gaps between the schooping and the metallic film could also pose serious thermal danger to the affected capacitor. Fusing current modelling and experimental measurement showed that fusing in metallic films typically occurred for current densities of several hundred thousand amperes per square centimetre. The partial disconnection of the metallic layers from the schooping edge by corrosion for example, was shown to result in large increases in dissipation factor and power loss in a capacitor readily explaining how capacitors

This dissertation investigates the three-stage method MEAUS (melt-extrusion, annealing, and uniaxial stretching) for producing microporous membranes. This method for membrane preparation is a solvent-free process based on the stretching of semicrystalline polymer films containing a row-nucleated lamellar structure. In this regard, the first section of this thesis is dedicated to establishing an initial set of requirements based on the ability of different polyolefin materials for the formation of microporous membranes. The influence of the polymer matrix composition and the architecture structure on the flow-induced crystallization was studied. This was done using two linear polypropylenes having different molecular weights, and blending them with branched and very fluid PP resins. Lower porosity and permeability values were observed when low molecular weight polypropylenes were employed. Under the same processing conditions, the more prolonged relaxation time behavior of high molecular weight resins constituted the main factor in maintaining the macromolecular alignment for the generation of a row-lamellar crystalline structure. In the second part of this research work, heterophasic and random copolymers of polypropylene–ethylene were selected to study the influence of ethylene comonomer and its distribution along the polymer backbone. Most of these polymers can form a planar stacked lamellar morphology with a high crystalline orientation by selecting appropriate processing conditions. From a process engineering standpoint, the influence of the extrusion draw ratio was analysed, and in-depth study concerning the annealing and uniaxial strain stages was performed. After annealing, the films were subjected to a uniaxially stretching step where the films are deformed along the machine direction. First, to generate pores at room temperature and subsequently stretched at a high temperature to enlarge the pore size by increasing lamellar separation. This thesis was also conducted as part of a comprehensive study aimed at evaluating the effect of temperature in the stages of extrusion, annealing, and uniaxial strain, as well as the use in some cases of extreme strain rates and strain extents. High levels of molecular orientation can be obtained with high extrusion draw ratios and fast cooling. Regarding the annealing process, an increment in temperature gave rise to a greater molecular orientation and a rearrangement of polymer chains in both the crystalline and amorphous phases, which led to an increase in crystallinity and molecular orientation. A close relationship was found between the starting crystalline characteristics and annealing and stretching conditions that affected the final porous morphology, and the trends registered for permeability. The last section of this thesis is devoted to ascertaining the effects of mineral fillers (CaCO3 and talc) on the crystallization and mechanical behavior of multilayer polypropylene/high density polyethylene microporous membranes. Celgard initially developed PP/PE/PP trilayer separators. This multilayer system can be produced by various processes such as lamination and co-extrusion, which allows combining the lower melting temperature of PE with the high-temperature strength of PP. The crystallization and crystalline orientation were affected by both the flow-induced crystallization and the nucleating mechanism of the fillers. A synergistic effect was observed in the filled samples due to the generation of pores during the uniaxial stretching stages (MEAUS method) along with the debonding mechanisms of mineral fillers from the polymeric matrix, which promoted the formation of larger pores giving rise to a change in membrane permeability. The agglomeration of fillers in the composites affected the mechanical properties, the average membrane pore size, and pore size distribution.
En esta tesis doctoral se investiga el método extrusión en fundido, recocido y estiramiento uniaxial (MEAUS, por sus siglas en inglés) para el desarrollo de membranas microporosas. Este método para la preparación de muestras porosas no parte de ninguna solución líquida de polímero, si no que un proceso basado en el estiramiento de películas hechas a partir de termoplásticos semicristalinos que contienen una estructura no esferulítica denominada estructura "row-nucleated" (estructura nucleada en fila o de lamelas apiladas). La primera parte de esta tesis está dedicada a establecer un conjunto de requisitos iniciales basados en la capacidad de diferentes poliolefinas para la formación de membranas microporosas. Se estudió la influencia de la composición y estructura del polímero en su proceso de cristalización seleccionando distintos grados comerciales de polipropileno homopolímero, con diferentes promedios de peso molecular, así como un polipropileno con ramificación de cadena larga. En las membranas hechas a partir de polipropilenos de menor peso molecular se obtuvieron valores más bajos tanto de porosidad como de permeabilidad. Bajo las mismas condiciones de procesamiento, el mayor tiempo de relajación de las resinas con mayor peso molecular constituyó un factor clave a la hora de mantener la orientación molecular deseada. En la segunda parte de este trabajo de investigación se seleccionaron dos tipos de copolimero de propileno-etileno (copolimero heterofásico y copolimero al azar), con el objetivo de estudiar la influencia de esta segunda fase y su distribución a lo largo de la cadena principal del material. La mayoría de los polímeros investigados han tenido la capacidad de desarrollar la estructura de lamelas apiladas "row-nucleated" aplicando las condiciones óptimas de procesado. Teniendo en cuenta las diferentes etapas de fabricación de las que consta este método, se ha realizado un estudio en profundidad sobre la influencia que tiene tanto la relación de estirado aplicada durante el proceso de extrusión, como la de las etapas de recocido y estiramiento uniaxial en el desarrollo de la estructura porosa. Tras el recocido de las muestras, los films son sometidos a una etapa de estiramiento a dos temperaturas diferentes. En primer lugar, el film recocido es estirado uniaxialmente a baja temperatura con el fin de nuclear poros en el interior de la estructura cristalina. Posteriormente, la misma muestra es estirada uniaxialmente a mayor temperatura con el objetivo de agrandar el tamaño promedio de poro. En esta tesis también se ha evaluado el efecto que tiene la variable de temperatura en las etapas de extrusión, recocido y estiramiento. La última sección de esta tesis está dedicada a determinar el efecto de la incorporación de distintas cargas minerales (CaCO3 y talco) en la cristalización y el comportamiento mecánico de membranas multicapa polipropileno / polietileno de alta densidad. Este sistema multicapa se puede obtener mediante diferentes métodos de procesado tales como la laminación y la coextrusión, los cuales permiten combinar la temperatura de fusión más baja del PE con la resistencia a la alta temperatura del PP. El proceso de cristalización y orientación de las muestras se vio afectado tanto por las variables descritas anteriormente, como por los mecanismos de nucleación y cristalización producidas por la presencia de las cargas minerales. En estas muestras compuestas se observó la presencia de poros de mayor tamaño fruto de la combinación de dos fenómenos distintos. Por un lado, la separación lamelar producida durante las etapas de estiramiento uniaxial y por otro, la separación producida entre las cargas inorgánicas y la matriz de polímero tras ser sometidos ambos a esfuerzos externos. La presencia de aglomerados en estos materiales compuestos influyó tanto en las propiedades mecánicas, como en el tamaño promedio y distribución de poros

The development of a new catalyst system by The Dow Chemical Company has resulted in the production of isotactic polypropylene and propylene/ethylene copolymers with a unique defect and comonomer distribution. This work investigated the morphology and optical properties of cast and compression molded films made from the homopolymer and copolymers with up to 20 mol% ethylene comonomer. The defect distribution of the Dow Chemical copolymers resulted in materials with lower crystallinity than Ziegler-Natta or metallocene-made materials of similar ethylene content. These materials exhibited a gamma-phase crystal content ranging from 0-95%, depending on ethylene content, processing condition, and catalyst type. The gamma-phase crystal content of quiescently crystallized copolymer films was found to significantly influence their bulk optical properties, presumably through a change in the spherulite birefringence. The bulk haze, clarity, and transparency of a homopolymer film were degraded through annealing treatments, which decreased the fraction of gamma-phase crystallinity and increased the thickness of existing lamellae, resulting in an increased intensity of scattered light and a corresponding degradation in the optical properties of the film. The haze, clarity, transparency, and gloss of the copolymer films were found to improve at higher comonomer content and higher cooling rates. The variation in the length scale and degree of disorder in the bulk morphology of films processed under different conditions was shown to correlate with the optical quality of the films, with smaller scale morphologies scattering less light and resulting in films with better optical properties. It was also shown that no single metric can completely describe the optical quality of a polymer film; the relative importance of haze, transparency, and gloss, which depends on the intended application of the film, was discussed. The influence of surface scattering from the films was controlled through the compression molding of films using substrates of different surface roughness. The contribution of light scattered from the surface of the films was isolated and found to play a significant role in the degradation of optical quality.

O modo de vida consumista, presente na sociedade moderna, está diretamente relacionado ao problema dos resíduos gerados pela atividade do setor econômico, tanto na produção quanto no pós-consumo desses bens. Neste contexto, é possível considerar o setor alimentício como responsável por grande produção de resíduos poliméricos (plásticos), bastantes utilizados na produção de embalagens. A reciclagem destes polímeros constitui umas das principais soluções para o reaproveitamento desse material, porém, nem todo tipo de polímero possui reciclagem em grande escala no Brasil. Como o caso da película de polipropileno biorientado (BOPP), que apesar de muito empregado, é exemplo de material polimérico não priorizado pelas cooperativas de catadores e sucateiros por não ser de interesse da indústria de reciclagem nacional, dadas as características de sua composição. Uma possibilidade para o reaproveitamento do BOPP constitui a produção de painéis aglomerados de partículas de madeira em consórcio com tal material. Assim, este trabalho tem como objetivo avaliar a potencialidade de painéis híbridos produzidos a partir de partículas de resíduos de madeiras e de BOPP e resina poliuretana à base de óleo de mamona para uso como piso em edificações, por intermédio de ensaios laboratoriais de desempenho físico e mecânico dos mesmos. Foram encontrados os resultados: 768 kg/m³ para densidade; 1,63% para inchamento em espessura 2h e 4,03% para 24h; 8,3% para absorção de água em 2h e 19,95% para 24h; porosidade de 41,01%; 0,48 MPa de resistência à tração perpendicular; 716,88 N de resistência ao arranchamento de parafuso para face e 950,81 N para topo; 2,96 μm de rugosidade superficial; 0,2145 mm em perda de espessura por abrasão; 0,28 mm de endentação por queda de esfera; 0,057 mm de endentação para cargas em pequenas áreas; 0,319 mm de endentação por carga rolante; coeficiente de atrito estático de 0,372 e dinâmico de 0,231. Os resultados alcançados para os ensaios realizados demonstram a alta potencialidade dos painéis de partículas híbridos de madeira e BOPP desenvolvidos neste trabalho.
Consumerist way of life, present in modern society, is directly related to residues problem generated by economic sector activity, both in production and in post-consumption of these goods. In this context, it is possible to consider food sector as responsible for large polymer waste (plastics) production, quite used in packaging production. These recycling polymers constitutes one of the main solutions for this material reutilization, however, not every polymer type has large-scale recycling in Brazil. As in the case of biaxially oriented polypropylene film (BOPP), which although very employed, is an example of polymeric material not prioritized by scavengers cooperatives and scrappers because it is not yet of interest to national recycling industry, given its composition characteristics. One possibility for BOPP reuse is agglomerated panels production of wood particles in consortium with such material. Thus, this work aims to evaluate the potentiality of hybrid panels produced from wood waste and BOPP particles and polyurethane resin based on castor oil for use as flooring in buildings, by means of laboratory tests of their physical and mechanical performance. Results found were: 768 kg/m³ for density; 1.63% for swelling in thickness (2h) and 4.03% (24h); 8.3% for water absorption (2h) and 19.95% (24h); porosity 41.01%; 0.48 MPa of internal bond; 716.88 N of resistance to screw pullout to face and 950.81 N of top; 2.96 μm of surface roughness; 0.2145 mm in thickness loss by abrasion; 0.28 mm in indentation by ball drop; 0.057 mm of indentations for loads in small areas; 0.319 mm of indentation by rolling load; coefficient of static friction 0.372 and dynamic 0.231. Results achieved for tests carried out demonstrate that hybrid wood and BOPP particle panels developed in this work high potentiality.
