We propose a novel approach for synthesizing silicon surfaces ensuring arbitrary apparent contact angle within the range from 0° to 170° for water. Superhydrophilicity of silicon substrates is achieved by nanosecond laser treatment and subsequent change in the contact angle is obtained by deposition of fluoropolymer films with different thicknesses by a hot wire chemical vapor deposition (HWCVD) method. The deposited film thickness needed to obtain superhydrophobicity was determined. The wettability properties of the produced fluoropolymer-silicon system are analyzed using the Wenzel and Cassie theories.
