1. A method of preparing a chemically cross-linked elastic Parylene or poly(para-xylylene) (PPX) polymer film, comprising:
mixing a substituted paracyclophane and a vinyl-functionalized paracyclophane to form a mixture; and
co-polymerizing the mixture via a chemical vapor deposition polymerization (CVDP) process on a substrate to form the chemically cross-linked elastic polymer film,
wherein the chemically cross-linked elastic polymer film has a vinyl content of about 5% or less.
