可粘贴超疏水薄膜的制备

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.
