摘要: 以乙酰丙酮为偶联剂,应用溶胶-凝胶法制备了聚甲基丙烯酸甲酯(PMMA)/TiO2-SnO2有机无机杂化材料。采用红外光谱(FT-IR)、紫外光谱(UV)对PMMA/TiO2-SnO2进行表征,并测定其TG性质。结果表明:在聚合反应过程中,有机聚合物和无机组分之间通过共价键相连,并且该杂化材料具有良好的抗紫外光辐射性能和热稳定性能。Abstract: PMMA/TiO2-SnO2 hybrid materials were synthesized through sol-gel process using acetylacetone as coupling agent. The hybrid materials were characterized by FT-IR, UV spectroscopy and TG. The results show that organic polymers and inorganic components combine covalent bond during the polymerization, and the hybrid materials show good UV resistance and thermal stability.
