Development and characterization Of bio based polymer composites for High performance applications

Abstract

The present work attempted to prepare biobased polymer matrices and their composites using biobased precursor materials and reinforcements. Biobased polymers and their composites have advantages such as low expenditure, ecofriendly, green chemistry and shows better performances compared to conventional petrochemical based polymer composites. Easily polymerizing vegetable oils, naturally occurring phenolic compounds and abundant technology for the preparation of biobased reinforcements are notable advantages for the development of polymer matrices and their polymeric composites. Moreover, the biobased polymer matrices and their composites find applications in wide range like adhesives, coatings, construction engineering, consumer goods, automotive and pharmaceutical industry as similar to petrochemical based polymer composites. Further, polyurethane and polybenzoxazine derived from biobased resources have individuality due to the low price, inherent biodegradability, green chemistry, simple preparation techniques, easy structural modification to reduce high temperature curing, renewable, eco-friendly and social concern. So, the present work used natural oil like brassica nigra oil (mustard oil), cardanol and eugenol as raw material for the synthesis of polyol and benzoxazine monomers for the development of polyurethane and polybenzoxazine matrices based composites using various types of reinforcements for rapid commercialization. Initially, brassica nigra oil based polyurethane composites have been synthesized and characterized by various analytical techniques such as fourier transform infrared, NMR, X-ray diffraction, scanning electron microscope, atomic force microscopy, DSC and TGA newline
