Comparison Study of Different Inorganic Silica Based Reinforcement Kaolin and 3-Clycyldiloxypropyl Trimethoxysilane on Mechanical, Water Uptake and Swelling Area Properties of Chitosan Composites

Summary/Abstract: The blending of chitosan with different types of silica-based reinforcement materials, kaolin clay and (3-glycidyloxypropyl) trimethoxysilane via solution casting method had been carried out. This study was focused on the mechanical, water uptake and swelling area comparison between chitosan/kaolin (referred as Cs/Kao) and chitosan/(3-glycidyloxypropyl) trimethoxysilane (Cs/GPTMS) composites. Fourier transform infra-red (FTIR) characterization was also conducted in this study for functional group analysis. Mechanical properties, such as tensile strength, elongation percentage and young’s modulus, were performed according to ASTM D882-02 standard method. Based on the mechanical test, it can be concluded that different types of silica-based reinforcement materials resulted different mechanical properties. The GPTMS filled chitosan had higher tensile strength value than Cs/Kao at 15% filler loading but lower in another concentrations. Moreover, water uptake and swelling area value of Cs/GPTMS was lower than Cs/Kao at 15% filler content.
