Preparation of Chitosan/SiO2 Hybrid Polymer Material via sol-gel Process

Abstract

Abstract: By use of chitosan, butyryric anhydride, methacryloxypropyl trimethyloxysilane(MPTMS), tetraethyloxysilane(TEOS), firstly butyrylchitosanMPTMSwas synthesized by Michael addition reaction, and then went on acid catalysizing solgel process, lastly transparent butyrylchitosan/SiO₂ hybrid polymer materials were prepared. FTIRwas used to characterize the structure. The results of SEM, TGAand Test of Mechanical Properties indicate that the preparation techniques have great effect on surface topography, thermal degradation temperature and mechanical properties of hybrid polymer materials.
