A method of forming a patterned polymer layer on a substrate and a substrate having a polymer layer formed by the method. The method includes providing a substrate comprising a first surface having a first surface energy and a pattern located on the substrate forming a second surface having a second, lower surface energy than the first surface, and selectively depositing a polymeric layer onto the first surface using a monomer material in an initiated chemical vapor deposition process, wherein the initiated chemical vapor deposition process is operated under supersaturation conditions during the deposition process.

A composite containing a fluorine-containing copolymer, an alkali metal salt, and an ionic liquid. The fluorine-containing copolymer essentially contains: a structural unit represented by formula (1): —[CR.sup.1R.sup.2—CR.sup.3R.sup.4]— wherein R.sup.1 to R.sup.4 are each independently H, F, Cl, CF.sub.3, or OR.sup.10, where R.sup.10 is an organic group having 1 to 8 carbon atoms, provided that at least one of R.sup.1 to R.sup.4 is F; and a structural unit represented by formula (2): —[CR.sup.5R.sup.6—CR.sup.7R.sup.8]— wherein R.sup.5 to R.sup.8 are each independently H, F, an alkyl group having 1 to 3 carbon atoms, a functional group containing a heteroatom other than the fluorine atom, or a group containing the functional group. At least one of R.sup.5 to R.sup.8 is a functional group containing a heteroatom other than the fluorine atom or a group containing the functional group, and the composite has a volatile content of 0.1 mass % or less.
