摘　　要：以芳纶织物为基底,利用溶胶凝胶法原位合成TiO_2-SiO_2复合溶胶织物。利用SEM、AFM、XRD等手段对织物进行了表征,并测试了复合溶胶织物紫外/可见光/近红外光波段的反射率和红外发射率。结果表明,织物表面TiO_2-SiO_2复合溶胶致密均匀,经水热处理后有突起的TiO_2粒子生成,结构为锐钛矿。水热处理加强了TiO_2-SiO_2复合溶胶织物对可见光和近红外波段光线的反射,降低了织物的红外发射率,增强了芳纶织物屏蔽红外光的功能性。Based on aramid fabric TiO2-SiO2 multiple sol fabric was in-situ synthesized using the sol-gel method. SEM, AFM and XRD was adopted to characterize the fabric, and reflectivity of UV/visible/nea^infrared light and infrared emissivity were tested. Results indicated that TiO2-SiO2 multiple sol on the surface of the amarid was dense and uniform, and TiOz particles were generated with anatase structure after hydrothermal treatment. Hydrothermal treatment strengthened reflectance to visible/near-infrared light and reduced infrared emissivity of TiO2- SiO2 multiple sol fabric, and enhanced functionality of aramid fabric in shielding infrared light field.
