The Preparation of a Superhydrophobic Fluorine Rubber Surface

Abstract

Superhydrophobic materials have a good application prospect in self-cleaning, anti-fouling, anti-corrosion, and anti-freezing. However, creating large areas of simple, efficient, and environmentally friendly superhydrophobic surfaces remains a huge challenge. In this paper, a simple, environmentally friendly surface superhydrophobic preparation method is used based on 107 silicone rubber adhesive. A superhydrophobic coating with a micro/nano structure was constructed on the surface of fluorine rubber. The particle size and groups of HB-192V powder (mainly SiO2) were observed by Fourier-transform infrared spectroscopy and a scanning electron microscope (SEM). The structures of two kinds of rubber surfaces were observed by SEM, and the superhydrophobic surface materials were qualitatively analyzed by X-ray diffraction (XRD). The hydrophobic properties of the superhydrophobic surface and the bouncing properties of droplets were analyzed by a contact angle measuring instrument and a high-speed camera. The results show that the preparation of superhydrophobic fluorine rubber on the surface of the water meter contact angle could reach an average of 154.1°. The superhydrophobic surface prepared by this method has a better hydrophobic and droplet bounce property.
