Fabrication of biomimetic super-amphiphobic surfaces through plasma modification of benzoxazine films

Abstract

In this study, a method for producing super-amphiphobic surfaces through plasma modification of benzoxazine films is presented. Microroughening and fluorination of the benzoxazine films occurs during the plasma treatment process and a rugged surface with a micro/nano binary structure is formed. The combined effect of low surface energy and substrate roughness results in high advancing contact angles (157 degrees for water, 152 degrees for diiodomethane) and low contact angle hysteresis.
