摘要： 以正丁酐(Butyricanhydride)、壳聚糖(Chitosan)、甲基丙烯酰氧基丙基三甲氧基硅烷(MPTMS)、正硅酸乙酯(TEOS)为原料,采用迈克尔加成反应合成了丁酰壳聚糖-MPTMS,配合酸催化sol-gel过程,制备了透明的壳聚糖/SiO2杂化材料.FTIR表征了杂化材料的结构.TGA,SEM以及力学性能测试结果表明,杂化材料的成型工艺对材料的表面形貌、热分解温度以及力学性能的影响显著.

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.
