Abstract
The preparation methods of the superhydrophobic surface play an important role in its application, but most of the existing preparation methods are complicated in operation, high in cost, and polluting to the environment. In order to find a simple, rapid, low-cost, and nonenvironmentally polluting preparation method of the superhydrophobic surface, this paper used liquid silicone rubber as the carrier. Before the liquid silicone rubber was nearly cured, it was evenly covered with a layer of silicon dioxide powder, and then 5 N weight was used to compact the powder on the rubber surface, so that the superhydrophobic surface was quickly formed on its surface. The wettability, bouncing performance, self-cleaning performance, and bending durability of liquid silicone rubber before and after treatment were compared. The results show that the static contact angle and rolling angle of the liquid silicone rubber after powder pressing were 158.22 ± 2.01° and 1.00 ± 0.50°, respectively. Moreover, the superhydrophobic surface formed by the powder pressing method had good self-cleaning performance, high temperature resistance, bending resistance, and excellent droplet bounce performance. The strategy of preparing a superhydrophobic surface by a one-step powder pressing method may be applied to the preparation of the superhydrophobic surface on a large scale.
