Blend of recycled polycarbonate/acrylonitrile butadiene styrene (R-PC/ABS), with virgin polycarbonate (VPC) and ethyl vinayl acetate grafted maleic anhydride (EVA-g-MAH) were prepared via melt blending techniques. Ethyl vinayl acetate (EVA) terpolymer grafted with maleic anhydride (MAH) to get EVA-g-MAH. Fourier Transform Infrared Spectroscopy (FTIR) spectra shows two new absorbance peaks at 1779 and 1851 cm-1, which correspond to symmetrical and asymmetrical stretching virbrations of MAH carbonyl (C O) group and the grafting ratio was calculated through chemical titration method. The R-PC/ABS blend properties was upgradated by the addition of 30 wt% VPC and 10 wt% EVA-g-MAH exhibited optimum impact performance to about 183.5 J/m, which is 48.1% higher than the R-PC/ABS blend. Dynamic mechnical analysis (DMA) and rheological results indicated that R-PC/ABS was partially miscible with VPC and EVA-g-MAH was an efficient reactive compatibilizer for R-PC/ABS blends. The morphology of prepared blend has been examined by using scanning electron micrscopy (SEM) and force modulation microscopy (FMM). © 2014 by American Scientific Publishers. All rights reserved.

Waste Management and Research | Year: 2014

This study is focused on the recovery and recycling of plastics waste, primarily polycarbonate, poly(acrylonitrile-butadiene-styrene) and high impact polystyrene, from end-of-life waste electrical and electronic equipments. Recycling of used polycarbonate, acrylonitrile-butadiene-styrene, polycarbonate/acrylonitrile-butadiene-styrene and acrylonitrile-butadiene- styrene/high impact polystrene material was carried out using material recycling through a melt blending process. An optimized blend composition was formulated to achieve desired properties from different plastics present in the waste electrical and electronic equipments. The toughness of blended plastics was improved with the addition of 10 wt% of virgin polycarbonate and impact modifier (ethylene-acrylic ester-glycidyl methacrylate). The mechanical, thermal, dynamic-mechanical and morphological properties of recycled blend were investigated. Improved properties of blended plastics indicate better miscibility in the presence of a compatibilizer suitable for high-end application. © The Author(s) 2014. Source

Composites Part A: Applied Science and Manufacturing | Year: 2015

The growing ecological and environmental consciousness has driven efforts for development of new innovative materials for various end-use applications. Polymers synthesized from natural resources, have gained considerable research interest in the recent years. This review paper is intended to provide a brief outline of work that covers in the area of biocomposites, major class of biodegradable polymers, natural fibres, as well as their manufacturing techniques and properties has been highlighted. Various surface modification methods were incorporated to improve the fibre-matrix adhesion resulting in the enhancement of mechanical properties of the biocomposites. Moreover, an economical impact and future direction of these materials has been critically reviewed. This review concludes that the biocomposites form one of the emerging areas in polymer science that gain attention for use in various applications ranging from automobile to the building industries. © 2015 Elsevier Ltd.

Extreme complexity in the range of polymer composition in waste printed circuit boards (WPCBs) will leave us to follow a series of steps to formulate an efficient recycling system. The current study deals with the recovery and utilisation of non-metallic fractions from WPCBs through dismantling, size reduction and sieve analysis. Density based techniques have been adopted in the current studies to separate the non-metallic fractions from metallic one due to its simplicity and cost effectiveness. The non-metallic fractions are quantified through sieve analysis and are utilised as reinforcing filler material in polypropylene matrix. Composite material with WPCBs has been prepared via melt blending techniques and is subjected to mechanical, thermal and morphological analysis to investigate its feasibility for automobile application. © Institute of Materials, Minerals and Mining 2015.
