Abstract

Chitosan exhibit great potential to be a critical part of the global sustainability solution; however, its
application areas are limited due to its inadequate properties for some applications. The use of chitosan is
limited because of several reasons such as performance (brittleness, poor barrier properties) and processing (low
thermal strength temperatures). The properties of chitosan depend on its molecular weight and there are not
enough studies in the literature. The application of nanoparticles to chitosan provides new advantages both in
improving the properties of chitosan and in reducing its costs. However, such nanoparticles can introduce some
difficulties. Nanoparticles additives increase transparency but cause agglomerates due to the high
surface/volume ratio, which reduces the local mechanical strength. Recently a novel particle technology, called
as MicNo®. MicNo® particles are designed micron size hexagonal plates which are composed of primary fine
particles. They only exhibit advantages of micron and nano size. For example, they exhibit superior surface
coverage (up to 70% mole) with respect to spherical particles while they are transparent. Accordingly, the
research goal of this study was to appraise effects of MicNo® and nano ZnO particles on structure development
and hence properties of medium molecular weight Chitosan/PVA films. The results show that MicNo® particles
improve UV-resistance and degree of crystallinity of the films and demonstrate great potential as new
generation additive systems for biodegradable polymers to extend their application areas.
