摘　　要：二氧化硅气凝胶(SA)有非常高的透光性,其纳米复合材料有优异的透光性能.实验在MMA-MTC本体聚合时加入SA,通过静电作用制备成P(MMA-MTC)/SA,分别与P(MMA-MTC),PMMA/SA,SA,PMMA和PMMA-KH570-SA试样进行对比分析;通过傅里叶变换红外光谱(FTIR)、热重分析(TG)、雾度仪和红外可见光分光光度计等手段对试样进行了表征.研究结果表明:聚合物静电作用有效地提高了SA的热稳定性、折射率和透光率等性能.Silica Aerogel(SA) has a very high light transmittance, its nanocomposites have excellent light transmission properties. In the experiment, SA is added to MMA-MTC bulk polymerization and P(MMA-MTC)/SA is prepared by electrostatic interaction, and compared with P(MMA-MTC), PMMA/SA, SA, PMMA and PMMA-KH570-SA samples respectively. The samples are characterized by Fourier transform infrared(FTIR) spectroscopy, thermogravimetric analysis(TG), haze meter, and infrared visible light spectrophotometer. The research results show that the electrostatic effect of the polymer effectively improves the thermal stability, refractive index and light transmittance of SA.
