A method of coating a surface with a polymer layer, which method comprises exposing said surface to a plasma comprising an optionally substituted alkyne so as to form an oil or water repellent coating on said substrate. Suitable compounds for use in the methods are compounds of formula (I) R<4>-C I C-X-R<5> where R<4> is hydrogen, alkyl, cycloalkyl, haloalkyl or aryl optionally substituted by halo; X is a bond or a bridging group; and R<5> is an alkyl, cycloalkyl or aryl group optionally substituted by halogen. The method is particularly useful in the production of oil and/or water repellent fabrics. |
