Abstract

A simple and robust method for fabrication of superamphiphobic surfaces by template-free chemical deposition of Cu micro-cone arrays, followed by air plasma activation and room-temperature treatment in tridecafluoro-1,1,2,2-tetrahydrooctyl trichlorosilane (FTS) is reported in this paper. After only treatment with 15 min of FTS, a water contact angle of 166.1° and an oil (diiodomethane, CH 2 I 2 ) contact angle of 160.5° are reached on the Cu surfaces. The highest oil contact angle of 168.1° is achieved after 1 h treatment with FTS. Such surfaces also display enhanced corrosion resistance due to the combination of the FTS layer and air pockets which prevent ion diffusion to the internal copper.
