Abstract:

Superhydrophobic high-transmittance antireflection coatings (ARCs) have significant potential for applications in optical devices such as microscope lenses, as well as in daily life for windows and glasses. However, current technologies encounter challenges in achieving superhydrophobicity on surfaces of ARCs. Here, we successfully combine the initiated chemical vapor deposition (iCVD) process technology with surface structuring to obtain a wide-spectrum transmission-enhanced coatings exhibiting self-cleaning and superhydrophobic properties. Compared with the bared substrate, the average transmittance of the worm-like/nanocones structure increases from 93.0 % to 95.1 %. Furthermore, an impressive water contact angle of 177.1° and a sliding angle of less than 1.0° are achieved. Moreover, the transmittance and hydrophobic properties can be easily adjusted by manipulating morphology of the film. The formation mechanism and fabrication processes of nanocones and worm-like structures are comprehensively investigated for flexible adjustment of the film properties. This provides a practical solution for the application of ARCs in various scenarios.
