    Abstract: The purpose of the present disclosure is to provide a pre-coating processing method and a pre-coating processing system (1) for fiber-reinforced thermoplastic member, which can achieve the coating adherence required in the field of aircraft. In a pre-coating processing method according to the present disclosure, a to-be-coated surface of a fiber-reinforced thermoplastic plastic member (2) is subjected to an activation treatment: in which the to-be-coated surface is activated under a condition such that the surface free energy of the to-be-coated surface immediately after the activation treatment reaches at least 70 mJ/m2; and in which the to-be-coated surface is heated to a temperature at which the modulus of elasticity of the to-be-coated surface becomes lower than that at normal temperature.

    Abstract: A superhydrophobic and self-cleaning surface including a substrate and a superhydrophobic layer. The superhydrophobic layer having a reacted form of octadecyltrichlorosilane. The octadecyltrichlorosilane is disposed on and crosslinked to a surface of the substrate via surface hydroxyl groups. The surface exhibits a rms roughness of 40 nm to 60 nm, a water contact angle of 155° to 180°, and a contact angle hysteresis of less than 15°. A method of preparing the substrate with a superhydrophobic and self-cleaning surface including treating a substrate with a plasma treatment, contacting the substrate with water or an alcohol to form an hydroxylated substrate, contacting the hydroxylated substrate with a solution of octadecyltrichlorosilane in an alkane solvent at a concentration in the range of 0.05 M to 0.3 M, and drying the solution on to the substrate under ambient air to form the superhydrophobic and self-cleaning surface on the substrate.
