溶胶凝胶法聚醋酸乙烯酯/二氧化硅有机无机杂化材料的制备及表征

Synthesis and Characterization of PVAc- SiO_2 Organic- Inorganic Hybrid Materials

通过溶胶 -凝胶方法制备了均匀透明的 PVAc- Si O2 有机无机杂化材料 ,用 FT- IR、SEM及溶剂抽提对材料进行了结构表征 ,用

The PVAc- Si O2 hybrid materials have been prepared by in situ polymerization of tetrathoxysilane in the presence of PVAc.FT- IR,SEM and solventextraction were used to analyze the chemical structure.The physical properties of the materials were showed by DSC and density measurement.
