Title: NANO - ZINC OXIDE: A Novel Modifier for Thermoplastics
Author: Aswathy, K V; Dr. Rani, Joseph
Abstract: Various synthesis routes have been developed in recent years for the preparation of nanoparticles. One of those methods is polymer induced crystallization. The first objective of the present work was to prepare nano ZnO powder by polymer induced crystallization in chitosan solution and to characterize the material using different techniques like TEM, SEM, XRD, FTLR, UV spectroscopy, TGA, DSC etc.The second object of the study is to prepare composites using nano ZnO. It has been undertaken to explore the potential of nano ZnO as reinforcement in engineering as well as commodity thermoplastics to widen their application spectra. We selected three engineering thermoplastics like [poly ethylene terephthalate, polyamide 6, and polycarbonate] and three commodity plastics like [polypropylene, high density polyethylene, and polystyrene] for the study. To date one of the few disadvantages associated with nanoparticle incorporation has concerned toughness and impact performance. Modification of polymers could reduce impact performance. The present study also focused on whether nano ZnO can act as a modifier for thennoplastics, without sacrificing their impact strength.
