Texto completoThe current trend in food packaging is oriented towards the substitution of non-biodegradable petroleum-based polymers by packaging materials that are eco-friendly and can prolong the food shelf life as well. In this context, this Ph.D. project aims to the development of chitosan-based blend films enriched with natural (essential oils) and synthetic (ethyl lauroyl arginate) antimicrobial compounds for sustainable food packaging applications. The overall project has been divided into five main parts. The brief description of each chapter is presented here: Chapter I presents a brief introduction to the recent advances of chitosan-based blend films for food packaging applications. The reason for selecting chitosan as the main biopolymer in this study and literature review concerning blending chitosan with other biopolymers has been described. Chapter II aims to develop blend and bilayer bio-based active films by solvent casting technique, using chitosan and gelatin as biopolymers, glycerol as a plasticizer and ethyl lauroyl arginate (LAE) as an antimicrobial compound. The results showed that blend films had higher tensile strength and elastic modulus and lower water vapor permeability than bilayer films (p<0.05). Bilayer films demonstrated as effective barriers against UV light and showed lower transparency values (p<0.05). FT-IR spectra indicated that interactions existed between chitosan and gelatin due to electrostatic interactions and hydrogen bond formation. However, the addition of LAE did not interfere in the network structure. Active films containing LAE (0.1%, v/v) inhibited the growth of four food bacterial pathogens including Listeria monocytogenes, Escherichia coli, Salmonella typhimurium, and Campylobacter jejuni. Chapter III focuses to develop films based on chitosan-gelatin blend enriched with cinnamon, citronella, pink clove, nutmeg, and thyme essential oils (1%, v/v) and evaluating their physical, optical, mechanical, water barrier and microstructural properties for active food packaging applications. The results confirmed intermolecular interactions between functional groups of the essential oils with the hydroxyl and amino groups of the chitosan-gelatin film network. The incorporation of different essential oils notably improved the UV barrier properties. The developed films, with special regards for those including thyme essential oil, were effective against four common food bacterial pathogens. Chapter IV aims to develop active films based on blending chitosan and polyvinyl alcohol enriched with LAE at different concentrations (1-10%, w/w). The results showed that high LAE levels negatively affected mechanical and water barrier properties. Addition of LAE improved UV barrier properties. The developed active films were effective against four common food bacterial pathogens.

Texto completoBlending polymers together offers researchers the ability to create novel materials that have a combination of desired properties of the individual polymers for a variety of functions as well as improving specific properties. The behaviour of the resulting blended polymer or blend is determined by the interactions between the two polymers. The resultant synergy from blending an intrinsically conducting polymer like polyaniline (PANI), is that it possesses the electrical, electronic, magnetic and optical properties of a metal while retaining the poor mechanical properties, solubility and processibility commonly associated with a conventional polymer. Aromatic polyamic acid has outstanding thermal, mechanical, electrical, and solvent resistance properties that can overcome the poor mechanical properties and instability of the conventional conducting polymers, such as polyaniline.

Polymeric membranes have been playing important roles in gas or liquid separations. Polyimide polymers are of interest due to their commercially availability along with good transport, thermal and mechanical properties. In this study, two common commercial polyimide polymers, Matrimid and P84 were blended, to combine the good transport property of Matrimid with the plasticization resistance of P84. Matrimid/P84 blend solutions ranging from 0-100 wt. % Matrimid were prepared to make blend films. Physical properties (density, d-spacing, thickness), transport properties (permeability of H2, N2, CH4, Ar, He, CO2, and gas pairs selectivity), thermal property (mass loss curves of TGA), and liquid solutes (water, methanol, toluene, butanol, 1-propanol, 2-propanol) desorption behavior were measured or characterized. Rules of changing behavior of the properties with mass fraction of Matrimid were investigated, summarized, and interpreted mathematically. As Matrimid mass fraction increases, there are more mobility and space between polymer chains, therefore there are smaller density, larger d-spacing, larger fractional free volume (FFV) and larger permeability. The selectivity-permeability relationship follows the trade-off line. Thermal mass loss curve of the blend films in air have presented intermediate characteristic with rising fraction of Matrimid compared to individual polymers. A partial-miscible behavior has been found from the correlation between permeability and FFV. The desorption behavior was found to be reasonably described by the case III model, where the diffusion rate is similar with relaxation rate of polymers.

Texto completoThis study is a contribution to the development of a new biomaterial with suitable melt strength, stiffness-to-toughness balance, and the required thermal performance for food packaging applications. The proposed approach consists in preparing a mixture of poly (lactic acid) [PLA] / polyamide 11 [PA11] with different compositions; the main advantage being to offer a range of properties that are difficult to combine on the same polymer. The different formulations, PLA/PA11, processed in the molten state in a twin-screw extruder were studied from the side of rheological, thermal, mechanical and morphology. Different copolymers of various structures were used, at different rates, in order to promote the adhesion in the interface of the components and to improve the blend systems performances. The aim is to obtain a formulation that having an elongation behavior, in the molten state, perfectly compatible with the blowing process

Texto completoThe formation of thin films of polymer blends by spin-coating from solution is characterised by rapid solvent quenching, a process that results in non-equilibrium morphologies. Thin films of conjugated polymer blends are used as the active material in polymer solar cells, in which the morphology may have drastic effects on device performance.
In this thesis results from morphology studies are presented for spin-coated thin films of polyfluorenes and co-polymers of polyfluorene blended with the fullerene derivative [6,6]-phenyl-C61-butyric acid methyl ester (PCBM). The surface morphology was investigated by atomic force microscopy (AFM) and was found to depend on the blend ratio as well as the chemical structure of the blend components. The spin speed, which determines the thickness of the spin-coated thin films, was also found to influence the morphology. Secondary ion mass spectrometry (SIMS) was used for depth profiling of the chemical composition in thin films of poly[(9,9-dioctylfluorenyl-2,7-diyl)-co-5,5-(4´,7´-di-2-thienyl-2´,1´,3´-benzothiadiazole)] (LBPF5) blended with PCBM. The films were found to be vertically phase separated with a four-fold multilayered structure.
