Abstract
Nano coir cellulose whiskersare materials abstracted from mesocarp of coconut shell which was modified by using KH570 as a coupling agent and modified nano coir cellulose whiskers need to be dispersed in chitosan/polyvinyl alcohol (CS/PVA) mixture solution. Because of regular structure and high crystallinity, nano coir cellulose whiskers could be applied in medical materials.In this paper, the results obtained with solution casting method by characterizing and analyzing structure, thermal properties, crystallization behavior and morphology of nano coir cellulose whiskers enhanced CS/PVA composite filmby FTIR, DSC, TG, XRD and SEM test. Different content of modified nano coir whiskers and CS/PVA composite film were preparedand themechanical properties of the composite film were also conducted. The results show that the tensile strength and Young's modulus of the CS/PVA composite film with modified nano coir whiskers are significantly improved, and Elongation break increases at first and then decreases, which indicates nano coir cellulose whiskers are good materials for medical purpose.
