Abstract:

Silver nanowires and hydrophobic nano-silica were coated on the surface of polyimide film by a simple pulling method. During the process, the conductive network and superhydrophobic coating were constructed respectively. The results show that the static contact angle of water droplets on the surface of the film is as high as 156.4°, and the rolling angle is less than 1°, indicating that the film has excellent superhydrophobic characteristics. At the same time, the film maintains high light transmittance, and its light transmittance is higher than 90%. The construction of silver nanowire network effectively increases the conductivity of the film, making the surface resistance of the film between 106—1010 Ω, meeting the anti-static requirements. In short, through the construction of conductive network and hydrophobic coating, the unity of transparent, antistatic and superhydrophobic functions is realized.

Key words: Multifunctional film, Hydrophobicity, Transparenty, Antistatic property
