大气压等离子体沉积棉织物类氧化硅薄膜

摘要

使用特殊的等离子体处理前HMDS0单体表面吸附和干燥的方法处理棉织物,通过大气压等离子体技术,成功地在棉织物表面沉积类氧化硅等离子体薄膜.使用SEM和FTIR分析了棉织物表面薄膜的形貌和化学结构.结果表明,棉纤维表面包覆了一层均匀连续的颗粒堆积薄膜,该薄膜中包含Si-O-Si和Si-O-C官能团.由于等离子体无机类氧化硅涂层,提高了棉织物的抗紫外和耐洗牢度.%Plasma treated cotton fabric is generated at atmosphere by a special pretreated method of HMDSO absorb and dry. The surface morphology and chemical structure of plasma treated cotton fabrics are analyzed by SEM and FTIR analysis. The results show that a SiOx-like film from the staring monomer of HMDSO is successfully deposited on cotton fabric at atmospheric pressure. This inorganic film is a particulate-accumulated film which contained Si-O-Si and Si-O-C functional groups. The UVabsorption and wash fastness of cotton fabrics are also greatly enhanced after this pretreat and plasma modification.
