摘要:
为了满足纺织品在使用过程中防污和隔热的需求，制备了一种自清洁隔热涂层织物。以正硅酸乙酯（TEOS）和六水合氯化铝（AlCl3·6H2O）为前驱体，使用溶胶-凝胶法制备了SiO2-Al2O3复合气凝胶，并将其均匀分散于聚二甲基硅氧烷（PDMS）溶液中，得到整理工作液；进一步以工作液浸渍整理涤纶织物，制备得到SiO2-Al2O3复合气凝胶整理的涤纶织物；采用场发射电子扫描显微镜、水接触角仪、导热系数仪和自清洁性能测试等技术，对整理后的涤纶织物进行结构和性能分析。结果表明：当整理工作液中PDMS和复合气凝胶的质量分数均为10%时，复合气凝胶在织物表面形成了多级粗糙结构，水接触角达到了153°，织物表现出良好的自清洁性能；同时，由于复合气凝胶在织物表面及纤维空隙内部的均匀负载，使得整理后织物的导热系数降低到了0.0411 W/(m·K)，在40.0 ℃条件下织物上下表面的温差达到了(5.0±0.4) ℃，具有优异的保温隔热效果。该方法赋予了涂层整理涤纶织物一定的自清洁性能和隔热性能。
