Resistant amphiphobic textile coating by plasma induced polymerization of a pyrrole derivative grafted to silica nanoparticles and short fluorinated alkyl chains

Hydrophobic and oleophobic resistant coatings are realized on nylon cotton textiles by plasma induced polymerization of modified pyrrole monomers. This process creates a chemical bond between the polymer textile fibers for an improved mechanical adherence. A post-grafting with short fluorinated chains gives non-wetting properties. Two other improvements tested compared in terms adherence wetting The first one consists inducing crosslinking to improve adhesion coating, second grafting silica nanoparticles enhance amphiphobicity.
