Abstract

In a present study polymer-MFC compounds have been investigated in order to define chemically modified microfibrillated cellulose potential as filler for polyvinyl alcohol-based composites. The research objective was to improve fibre-matrix adhesion and examine the effect of epoxidised MFC reinforcement on the mechanical properties of PVA. The composites with different fibre contents were prepared. The mechanical properties of composites were characterised using Instronr 4505 Universal Tensile testing machine. The epoxidised MFC showed favourable results and increased the tensile strength and the Young's modulus of PVA. The Young's modulus reached the maximum at 1 wt. % epoxidised MFC content, then level off. Dynamic mechanical analysis (DMA) showed an increase of storage tensile modulus in the glassy state with increasing epoxidised-MFC content
