A Facile One-Step Preparation of Robust Superamphiphobic Cotton Fabric from a Crosslinkable POSS-Containing Fluorinated Acrylic Copolymer

The superamphiphobic surfaces typically have water and oil contact angles higher than 150° and widespread practical applications. However, developing a durable superamphiphobic material is emergent for practical applications. In this work, a robust superamphiphobic cotton fabric was obtained by a facile one-step dip-coating process with a crosslinkable POSS-containing fluorinated acrylic copolymer. The copolymer was synthesized via the free radical solution copolymerization. The coated fabric has a water contact angle of 153.2°, glycerol contact angle of 152.1° and ethylene glycol contact angle of 144.3°, showing both superhydrophobicity and high oleophobicity. Furthermore, the coated fabric could keep its amphiphobic property even after ultrasonic treatment in ethanol or thermal treatment, as well as for acid or alkaline liquids. This superamphiphobic cotton fabric prepared by the copolymer may have many potential applications due to its simple preparation process and excellent durability.
