A coated substrate includes: a substrate and a first layer on at least a portion of the substrate, the first layer including a polymer selected from the group consisting of an acrylic, an epoxy, a polyurethane, a copolymer thereof, and a mixture thereof, and an additive selected from the group consisting of an ultraviolet light (UV) absorber, a UV stabilizer, and a mixture thereof. The coated substrate further includes a second layer on at least a portion of the first layer, and a third layer on at least a portion of the second layer. A method of forming a coated substrate includes: forming a first layer on at least a portion of a substrate; forming a second layer on at least portion of the first layer; and forming a third layer by plasma enhanced chemical vapor deposition on at least a portion of the second layer.

A transparent wear-resistant film layer, a plastic substrate modification method, and a product are provided, the plastic substrate modification method includes the following steps: bombarding with at least one plastic substrate positioned in a chamber of a PECVD coating device with plasma to clean and activate the at least one plastic substrate, and forming a transparent wear-resistant film layer on the at least one surface of the activated plastic substrate by a plasma enhanced chemical vapor deposition using a siloxane monomer as a reaction raw material.

Drug-eluting polymer coatings for biomedical implants are disclosed, as well as assemblies and kits containing same. The polymer coatings are deposited on the biomedical implants via a solvent-free, chemical vapor deposition process. The polymer coatings exhibit controlled release of the drug with substantially no burst release and substantially linear release over time. Also disclosed are methods of making and using the coatings, assemblies, and kits.
