Highly Transparent Superhydrophobic Surfaces from Silica Aerogel by Sol-Gel Method

Abstract:

We study the preparation of thin film on the glass substrate with the method of dip coating, which is based on methanol and MTMS as raw materials, making them form silica aerogel by sol-gel method. Scanning electron micrographs (SEM) show that such a film possesses a porous three-dimensional network structure. The high porosity and low refractive index determine that the transmittance rate can reach 90%. The prepared film also exhibited apparent hydrophobic effect, with the contact angle of 156.3°and rolling angle of less than 10°. The transparency and superhydrophobic of the film make it suitable as multifunctional coatings for many application fields including solar cells, cellphones and a variety of electron device.
