Study on Thermal and Mechanical Properties of Cellulose Nanofibrils/PVA Composites
摘要
Abstract
The cellulose nanofibrils (CNFs)/polyvinyl alcohol (PVA) composite was prepared by solution casting. The effect of CNFs on thermal and mechanical properties of the composite were investigated by TG, DSC and DMA. The results show that the addition of CNFs increases the crystallinity and melting point of PVA, while with increase of CNFs content, the crystallinity and melting point of PVA decrease because of the hydrogen bond between CNFs and PVA, which limits the movement of PVA molecular chain; the addition of CNFs increases the glass transition temperature, tensile strength and elastic modulus of PVA, both tensile strength and elastic modulus of 2%/CNFs composite are up to the maximum values, which increase by 28.98% and 14.1% respectively than those of pure PVA.关键词
