The self-cleaning effects of polyethylene terephthalate fabric (PET) through the photocatalytic effects of TiO2 (T), porphyrin (P) and silane (S) have been explored ultrasonically using bath type (WUC-D22H, Daihan Scientific, Korea). The ultrasonic power and frequency were 100 W and 30 kHz, respectively. The surface modification in fabric was achieved by the ultrasonic deposition of anatase TiO2 (T)
使用浴液类型(WUC-D22H,Daihan Scientific,Korea)对超声波对TiO 2(T),卟啉(P)和硅烷(S)的光催化作用进行了研究,发现聚对苯二甲酸乙二酯织物(PET)的自清洁作用。超声功率和频率分别为100 W和30 kHz。超声沉积锐钛矿型TiO 2(T),卟啉(P),并通过硅烷(S)进一步改性实现了织物的表面改性。)被用来实现双重功能(光催化和超疏水)自清洁行为。通过可见光处理使各种有机污染物发生光致变色,证实了改性织物表面的染料降解能力。通过测试可见的各种染料,使用紫外可见光谱通过测量时间间隔改变后织物中浓度的变化来监测亚甲基蓝(MB)的分解。硅烷的附着及其在洗涤织物表面后的稳定性通过测量水接触角(WCA)来确认。自清洁效率依次为PET @ TP > PET @ TPS。修饰是在织物表面进行的,并通过XRD,XPS,UV-Vis和FESEM分析加以确认。织物的
