摘要：

为开发耐久性光催化自清洁纺织品，以聚偏氟乙烯（PVDF）与纳米TiO2 为原料，对涤纶织物进行涂层加工，制得具有光催化自清洁性能的纺织品。借助DigiEye 数码图像测色系统、扫描电子显微镜和能谱仪等对涂层织物的自清洁性能、自清洁涂层的耐磨性能以及自清洁涂层的耐老化性能进行测试。结果表明：随着纳米TiO2 质量分数的增加，涂层织物的自清洁效果增强，但涂层浆的流变性变差，自清洁涂层的均匀性降低，PVDF 对纳米TiO2 颗粒的黏合效果降低，自清洁涂层的耐磨性能下降，自清洁涂层的耐老化性能也逐渐下降；在纳米TiO2 质量分数为33.3%时，涂层浆流变性较好，自清洁涂层均匀性较好，涂层织物自清洁性能较好，且自清洁涂层的耐磨性能和耐老化性能较好。

Abstract:

Polyvinylidene fluoride (PVDF) resin and nano-TiO2 were used to treat polyester fabric as raw materials to prepare the durable textiles with the photo-catalytic self-cleaning properties. The self-cleaning properties of the coated fabric, the abrasion resistance of the self-cleaning coating and the aging resistance of the self-cleaning coating were tested by digital image colorimetric system, scanning electron microscopy and energy dispersive spectrometer. Result reveal that with the increase of the amount of TiO2, the self-cleaning effect of coated fabric is enhanced, but the rheological property of the coating pulp is deteriorated, the integrity of the self-cleaning coat is reduced, the bonding effect of PVDF to TiO2 is reduced, the abrasion resistance effect and aging resistance of self-cleaning coating are deteriorated. When the adosage of TiO2 is 33.3%, the rheological property of the coating pulp is better, the self-cleaning coat is even, the self-cleaning properties, the aging resistance and the abrasion resistance of the self-cleaning are also better.

Key words: photo-catalytic, self-cleaning, coated fabric, polyvinylidene fluoride, aging resistance
