Fabrication of Polydimethylsiloxane Superhydrophobic Coatings with Self-healing Properties Using the Template Method

The main factors hindering the applicability of superhydrophobic coatings are their complex preparation methods, high cost, and poor mechanical stability. To address some of these issues, coatings using polydimethylsiloxanes (PDMS) with good mechanical stability having self-healing properties were prepared by combining the sodium chloride particles template with flame treatment technology. This coating demonstrated good superhydrophobicity due to the micro/nanostructure on its surface having a maximum water contact angle of 163 degrees and a water sliding angle of less than 2 degrees. Moreover, it exhibited good mechanical stability, which was examined by tape peeling and sandpaper abrasion tests. It was also observed that the damaged PDMS coating recovered its superhydrophobicity after flame treatment due to the partial decomposition of the polymers. We have shown that high-quality PDMS superhydrophobic coating can be prepared with a low-cost and simple method, which has great applicability potential in frost resistance and self-cleaning.This title is mismatch with jobsheet title.
