摘要:

通过聚二甲基硅氧烷(PDMS)与碳纤维织物复合, 采用模板法在PDMS聚合物表面构筑微阵列结构, 制备了一种具有可重复粘贴性的超疏水薄膜. 研究结果表明, 该薄膜微结构表面的接触角为154°, 滚动角为14°, 具有低黏附的超疏水特性. 而PDMS与碳纤维织物的紧密结合, 赋予了超疏水薄膜较高的黏接力和力学性能, 断裂强度达到116.96 MPa. 所制备的超疏水薄膜可粘贴于多种材料表面, 同时经过30 d的长时间粘贴以及50次的循环粘贴后, 该薄膜依然保持着较高的黏附性能及超疏水特征, 表明超疏水薄膜具有良好的力学稳定性及耐久性, 满足长时间可重复使用的要求, 可应用于对破损超疏水涂层的快速、 大面积粘贴修复.

Abstract:

By combining polydimethylsiloxane(PDMS) and carbon fabric, a superhydrophobic film with repeated adhesion performance was fabricated by the introduction of microarray structure on the PDMS polymer surface with a template method. The results show that the contact angle and rolling angle on the microstructural surface of the thin film are 154° and 14°, respectively, having low adhesion superhydrophobicity performance. The close combination of PDMS and carbon fiber fabric can endow the superhydrophobic film with higher adhesion performance and mechanical property. The breaking strength reaches 116.96 MPa. The as-prepared superhydrophobic film can be adhered on different materials. After long time adhesion of 30 d and repeated adhesion of 50 times, the as-prepared film still maintains high adhesion and superhydrophobic properties, which shows that the superhydrophobic film has good mechanical stability and durability and can meet the requirements of reusability for a long time. It can be used to repair the large-area damaged super-hydrophobic coating quickly and efficiently.
