Argon-plasma reinforced superamphiphobic fabrics

A novel method for preparing durable superamphiphobic fabrics is reported, which involves preapplying a solution consisting of perfluoroalkyl acrylate, epoxide-containing silane, and silica nanoparticles onto fabric and subsequent argon-plasma treatment. The coated fabrics show superphobic to both water and oil fluids (surface tension >21.5 mN m-1 ). The coating is durable to withstand repeated laundries and multicycles of abrasion without apparently altering the superamphiphobicity. The coating is also very stable in boiling water, strong acid, and base, but has little effect on the fabric handle and air permeability. The argon-plasma-enhanced coating may offer a facile way to prepare durable superamphiphobic fabrics.
