Dargaville, Tim R. "Studies of the radiation chemistry and grafting of a fluoropolymer." Thesis, University of Queensland, 2002. https://eprints.qut.edu.au/33115/1/DARGAVILLE_PHD_THESIS.pdf.

Full text
Abstract:
The radiation chemistry and the grafting of a fluoropolymer, poly(tetrafluoroethylene-coperfluoropropyl vinyl ether) (PFA), was investigated with the aim of developing a highly stable grafted support for use in solid phase organic chemistry (SPOC). A radiation-induced grafting method was used whereby the PFA was exposed to ionizing radiation to form free radicals capable of initiating graft copolymerization of styrene. To fully investigate this process, both the radiation chemistry of PFA and the grafting of styrene to PFA were examined. Radiation alone was found to have a detrimental effect on PFA when irradiated at 303 K. This was evident from the loss in the mechanical properties due to chain scission reactions. This meant that when radiation was used for the grafting reactions, the total radiation dose needed to be kept as low as possible. The radicals produced when PFA was exposed to radiation were examined using electron spin resonance spectroscopy. Both main-chain (–CF2–C.F–CF2-) and end-chain (–CF2–C.F2) radicals were identified. The stability of the majority of the main-chain radicals when the polymer was heated above the glass transition temperature suggested that they were present mainly in the crystalline regions of the polymer, while the end-chain radicals were predominately located in the amorphous regions. The radical yield at 77 K was lower than the radical yield at 303 K suggesting that cage recombination at low temperatures inhibited free radicals from stabilizing. High-speed MAS 19F NMR was used to identify the non-volatile products after irradiation of PFA over a wide temperature range. The major products observed over the irradiation temperature 303 to 633 K included new saturated chain ends, short fluoromethyl side chains in both the amorphous and crystalline regions, and long branch points. The proportion of the radiolytic products shifted from mainly chain scission products at low irradiation temperatures to extensive branching at higher irradiation temperatures. Calculations of G values revealed that net crosslinking only occurred when PFA was irradiated in the melt. Minor products after irradiation at elevated temperatures included internal and terminal double bonds and CF3 groups adjacent to double bonds. The volatile products after irradiation at 303 K included tetrafluoromethane (CF4) and oxygen-containing species from loss of the perfluoropropyl ether side chains of PFA as identified by mass spectrometry and FTIR spectroscopy. The chemical changes induced by radiation exposure were accompanied by changes in the thermal properties of the polymer. Changes in the crystallinity and thermal stability of PFA after irradiation were examined using DSC and TGA techniques. The equilibrium melting temperature of untreated PFA was 599 K as determined using a method of extrapolation of the melting temperatures of imperfectly formed crystals. After low temperature irradiation, radiation- induced crystallization was prevalent due to scission of strained tie molecules, loss of perfluoropropyl ether side chains, and lowering of the molecular weight which promoted chain alignment and hence higher crystallinity. After irradiation at high temperatures, the presence of short and long branches hindered crystallization, lowering the overall crystallinity. The thermal stability of the PFA decreased with increasing radiation dose and temperature due to the introduction of defect groups. Styrene was graft copolymerized to PFA using -radiation as the initiation source with the aim of preparing a graft copolymer suitable as a support for SPOC. Various grafting conditions were studied, such as the total dose, dose rate, solvent effects and addition of nitroxides to create “living” graft chains. The effect of dose rate was examined when grafting styrene vapour to PFA using the simultaneous grafting method. The initial rate of grafting was found to be independent of the dose rate which implied that the reaction was diffusion controlled. When the styrene was dissolved in various solvents for the grafting reaction, the graft yield was strongly dependent of the type and concentration of the solvent used. The greatest graft yield was observed when the solvent swelled the grafted layers and the substrate. Microprobe Raman spectroscopy was used to map the penetration of the graft into the substrate. The grafted layer was found to contain both poly(styrene) (PS) and PFA and became thicker with increasing radiation dose and graft yield which showed that grafting began at the surface and progressively penetrated the substrate as the grafted layer was swollen. The molecular weight of the grafted PS was estimated by measuring the molecular weight of the non-covalently bonded homopolymer formed in the grafted layers using SEC. The molecular weight of the occluded homopolymer was an order of magnitude greater than the free homopolymer formed in the surrounding solution suggesting that the high viscosity in the grafted regions led to long PS grafts. When a nitroxide mediated free radical polymerization was used, grafting occurred within the substrate and not on the surface due to diffusion of styrene into the substrate at the high temperatures needed for the reaction to proceed. Loading tests were used to measure the capacity of the PS graft to be functionialized with aminomethyl groups then further derivatized. These loading tests showed that samples grafted in a solution of styrene and methanol had superior loading capacity over samples graft using other solvents due to the shallow penetration and hence better accessibility of the graft when methanol was used as a solvent.

Full text
Abstract:
High performance aromatic polymers such as PEEK and PEK are widely used in composite and related applications. However, their high rate thermomechanical properties are not well understood. This thesis describes a series of investigations into their mechanical behaviour over a large range of strain rates (10-3 -103 s-1 ) and temperatures (20-200° C) which were carried out in order to more fully understand their properties and to assess the applicability of standard polymer property models to their behaviour. The experiments involved the design and construction of two novel sets of high rate test apparatus. These were a cross-bow based system which enabled high strains to be obtained at strain rates of 103 s-1 and a drop-weight system based around a high speed camera which enabled direct measurements of radial strain and observation of sample behaviour to take place. The cross-bow apparatus incorporated a laser-photodiode system to enable direct strain measurements to be made and thus had an advantage over conventional Hopkinson bars of direct, rather than derived, strain measurements with a sufficiently energetic projectile to produce large deformations. These systems were used in addition to standard hydraulic ram and dropweight equipment. A heater unit to enable tests to be carried out over the desired temperature range was also designed and constructed and used with all the above systems. A comprehensive set of Differential Scanning Calorimetry and X-ray tests were carried out on samples before and after mechanical testing in order to provide structural data to aid the interpretation of the mechanical test results

Holland, John Richard. "Configurational properties of polyphenylene precursor polymers." Thesis, Durham University, 1993. http://etheses.dur.ac.uk/5654/.

Full text
Abstract:
The configurationally changes of a soluble precursor polymer. poly(5,6- dlmethylcarboxycyclohexadi-l.S-ene) have been studied during it’s conversion to poly(phenylene) by thermal aromatisation. This was performed principally in solution in N-methylpyirolidinone and chloroform, by size exclusion chromatography, viscometry and scattering techniques. The results show the polymer is initially a random coil, and during aromatisation stiffens to a wormlike chain, the intermediate to the rodlike molecule. This is evidenced by increased persistence length and increased dependency of size on molecular weight. The conversion to a stiffer molecule is accompanied by chain scission, more pronounced for high molecular weight polymers, and agglomeration, with consequential increased polydispersity and scatter in results. At 30% aromatisation aggregates dominate the behaviour of the solution, and at 40% the polymer becomes insoluble. Results from each technique differ according to the relative sensitivity to the two species present Aggregates exist as low as 10% aromatisation, suggesting the formation of contiguous phenylene nuclei, dispersed phenylene would not cause aggregation. When separated from the solution the aggregated species was found to be only slightly more aromatised than the free chain equivalent, and chemically very similar, suggesting aggregation arises from the arrangement rather than the quantity of phenylene monomers. The scattering behaviour of lightly aromatised polymer conformed to a wormlike chain model, while the aggregated polymer's scattering is close to that of a star model, suggesting a fringed micelle structure with a core of closely packed phenylene blocks, and arms preferentially composed of precursor polymer, with randomly dispersed phenylene. The insolubility of partially aromatised poly(DHCD-DMC) is common to other studies of polymers with conjugated backbones in which change from a good to a poor solvent causes a change from random coil to aggregated stiff chains.

Grandy, David Brian. "The micro-thermal analysis of polymers." Thesis, Loughborough University, 2002. https://dspace.lboro.ac.uk/2134/35677.

Full text
Abstract:
This study is concerned with the development of micro-thermal analysis as a technique for characterising heterogeneous polymers. It is divided into two main parts. In the first part, the use of miniature Wollaston wire near-field thermal probes mounted in an atomic force microscope (AFM) to carry out highly localised thermal analysis (L-TA) of amorphous and semi-crystalline polymers is investigated. Here, the temperature of the probe sensor or tip is scanned over a pre-selected temperature range while in contact with the surface of a sample. It is thereby used to heat a volume of material of the order of several cubic micrometres. The effect of the glass transition, cold crystallisation, melting and degree of crystallinity on L-TA measurements is investigated. The materials used are poly(ethylene terephthalate), polystyrene and fluorocarbon-coated poly(butylene terephthalate). The primary measurements are the micro- or localised analogues of thermomechanical analysis (L-TMA) and differential thermal analysis (L-DTA). The effect of applying a sinusoidal modulation to the temperature of the probe is also investigated.

Abstract:
Recently, the rapid and almost uncontrollable growth in the consumption of synthetic plastics in many sectors of the economy, especially in the field of packaging, has been a serious concern. Plastic containers are used for packaging food products, medicines, electronic devices, liquids, including those with a higher hazard class, etc. [1]. According to the German Nova-Institute, the global plastic production in 2020 has reached almost 400 Mill. Tons. At the same time, the volume of biodegradable plastics obtained from renewable resources amounted to only 3.5 million tons, i.e., about 1% of the total volume production [2]. Considering that only 25% of plastic waste is recycled, the growing consumption of polymer products is forcing manufacturers to develop biodegradable polymer compositions [3]. The problem has economic and environmental aspects since it is interconnected with the growing need to protect the environment and reduce the cost of raw materials for the production of various products.

Abstract:
Abstract Plastic trash has been building up for over a century in our landfills and oceans. Not only does it affect our wildlife, but the trash affects our lives by changing our oceans, our weather currents, and our food supply. To truly deplete the plastics that fill our landfills and oceans, a cost-effective and profitable method of plastic disposal, should be created. The heat transfer system will be used to heat plastics in such a way to break apart the polymer chains via pyrolysis, creating a vapor. The vapor will then be cooled where it will create petroleum oil, wax, and gaseous byproduct. This project research will continue by redesigning the furnace used in previous research, to get an accurate more stable heat that will reach the necessary boiling point of the plastics to create the vapor. Vapor will be collected through pipes and routed to a cooling unit, where it will be condensed, creating petroleum oil, a solid wax, and gaseous byproducts. Further research for oil optimization using variables such as types of plastics, temperature magnitudes and temperature rates from pyrolysis of synthetic polymers will aid in the creation of commercial/industrial sized pyrolysis systems that will be ecofriendly and economical.

Abstract:
Abstract Additive manufacturing (AM) techniques give access to completely new manufacturing processes. AM techniques using metals, ceramics, or plastics feedstock are predestined for lightweight construction and for components with complex shapes or internal functions. AM processing with plastics stands out due to the low density of polymers, a good process capability, and low initial costs. The properties of polymer components are extremely dependent on the utilized plastics and the reinforcements, e.g. in the form of fibres. Furthermore, coatings can improve the properties and enhance the possible range of applications for plastics. In the present study, PLA (polylactic acid) was printed utilizing Fused Layer Modeling (FLM). The surfaces of the PLA samples were directly structured with pits with different widths during printing. Subsequently, the surfaces were coated with ZnAl2 by means of Twin Wire Arc Spraying (TWAS). Adhesion tests meeting DIN EN 582 were conducted to measure the adhesion of the coating on the structured plastic surface. The results were compared to the adhesion of ZnAl2 coatings on grit blasted and as-built surfaces. Overall, the surface adhesion was significantly better for the samples with directly structured surfaces. Hence, a direct structuring of the surface during a 3D building process promises to be an outstanding possibility to prepare surfaces prior to coating processes.

Full text
Abstract:
The constitutive response of glassy polymers is characterized by their complex thermo-mechanical behavior such as strain rate and temperature sensitive yielding, softening at small strains and re-hardening at large strains. These complex behaviors trigger strain localization in the deformation of polymers. Since localization can be induced by both structural and material instabilities, careful analysis needs to be performed to investigate the localization behavior of polymer specimen testing. Localization such as neck formation and propagation that typically occurs in the tensile and compressive testing of polymers and plastics makes it difficult for experimentalists to extract their intrinsic constitutive response. This problem is exacerbated when localization occurs with shear bands. In this study, a macromolecular constitutive model for polymers showing small-strain softening and large-strain directional hardening is employed to investigate the effect of localization in tension onto the constitutive identification process. Considering the complex interplay between the structural and constitutive instabilities, a method based on direct, real-time measurement of area reduction at the neck section has been proposed to extract the intrinsic constitutive response of polymer materials.

Abstract:
The ubiquitous use of plastics in architectural design and construction obfuscates the very real human health risks which exist when polymers—derived from petroleum, coal, or natural gas—are used in the building industry. For more than fifty years, a majority of construction materials have been engineered using polymers for the purposes of achieving a range of advanced performance capacities. These materials are widely manipulated using fossil fuel derivatives for augmenting their structural strength, moisture resistance, form finding, or general resistance to weathering. Polyvinyl chlorides, for example, are used in plumbing supplies, exterior sheathing, interior surfaces, furniture, and landscaping, for these reasons. Indeed, nearly everything in our built environment is permeated by chemicals derived from fossil fuels. This is obviously problematic for carbon emissions: it is all the more critical in what concerns human health. More than half a century following the deliberate and orchestrated flooding of the construction market with inexpensive plastics, very little data is disclosed about the potential health risks associated with adopting such large quantities of nonrenewable, nonrecyclable, and wasteful materials. Architects, engineers, builders, clients, and the general public are poorly informed on the toxic accumulation of highly synthetic building polymers that originate in carbon-intensive fossil fuel industries and that saturate our air, water, and physical bodies. In response, this paper reports on the results of a funded research project aimed at identifying the sources, risks, and impacts of using such materials in the building industry. Funded by the Kleinman Center and the Penn Undergraduate Research Mentoring program at the University of Pennsylvania, the project studies site-specific material flows involved in the lifecycle of a set of polymers manufactured in the Philadelphia region. Invisible to most, yet present in many communities, are industrial sites which distill, manufacture, and fabricate the polymerized materials that pose the highest risks when building. This has been the case in the city of Philadelphia where for decades fossil fuels and their derivatives intended for the building industry have been manipulated, with risk. Sharing evidence of this, is the focus of this paper.

Abstract:
Abstract The improvement of the tribologic characteristics of surfaces is an important application of thermal sprayed coatings. Also various ranges of application demand good antiadhesive characteristics. The tribologic and antiadhesive characteristics of fluorine containing polymers are very good. Since furthermore those polymers have the highest thermal resistance of all plastics it has been investigated if those polymers can be integrated in thermal sprayed oxide and carbide coatings. The aim was to improve the tribologic and antiadhesive characteristics. The processes Plasma- and HVOF-spraying have been used to apply the coatings. The polymers in the coatings were detected by examinations with the light-optical and the scanning electron microscope. To heighten the contrast for the light microscopy examinations the metallographic sections of the specimens were physically contrasted. To clearly identify the different phases with the scanning electron microscope EDX-analyses have been carried out. Samples have been tested to investigate the mechanical characteristics of the coatings. Paper text in German.
