摘要
为制备具有亲水和防污自清洁性能的PVC建筑薄膜,在经低温等离子体改性的PVC薄膜表面涂覆SiO2作为隔离层,然后采用旋涂法将TiO2涂覆于薄膜表面,制备得到PVC/SiO2/TiO2复合膜。利用XRD、FTIR、SEM、EDS等测试手段对复合膜的形貌和结构进行表征,并用接触角测试仪测定了其亲水性能,经紫外光照后,复合膜的接触角由42.2°降为10.9°,结果表明TiO2层的涂覆大大地提高了PVC薄膜的亲水性能。
In order to prepare PVC architectural membrane with hydrophilic,anti-dirt and self-cleaning properties,SiO2 was coated on the surface of PVA film surface which was modified by low-temperature plasma.Then,spin-coating method was adopted to coat TiO2 on film surface to prepare PVC/SiO2/TiO2 composite membrane.The morphology and structure of the composite membrane were characterized with XRD、FTIR、EDS and SEM.Besides,the contact angle tester was used to measure hydrophilic property.After UV irradiation,the contact angle reduced from 42.2°to 10.9°.The results show that hydrophilic property of PVC membrane was improved greatly by TiO2 coating.
