Introduced here is a plasma polymerization apparatus and process. Example embodiments include a vacuum chamber in a substantially symmetrical shape to a central axis. A rotation rack may be operable to rotate about the central axis of the vacuum chamber. Additionally, reactive species discharge mechanisms positioned around a perimeter of the vacuum chamber in a substantially symmetrical manner from the outer perimeter of the vacuum chamber may be configured to disperse reactive species into the vacuum chamber. The reactive species may form a polymeric multi-layer coating on surfaces of the one or more devices. Each layer may have a different composition of atoms to enhance the water resistance, corrosion resistance, and fiction resistance of the polymeric multi-layer coating.

A method for forming an electrically conductive multi-layer coating with anti-corrosion properties and with a thickness comprised between 1 m and 10 m onto a substrate, comprising the following subsequent steps of (a) providing a suspension consisting of electrically conductive fillers into a matrix forming material; (b) depositing the suspension on at least a surface portion of a substrate; (c) exposing an atmospheric pressure plasma to the surface portion so as to form one electrically conductive layer with anti-corrosion properties; and (d) repeating the steps (a), (b) and (c). The method is remarkable in that the electrically conductive fillers are electrically conductive particles.

A process for preparing contact lens with film by plasma UV induced grafting polymerization is disclosed to plasma-modification on contact lens to form hydrophilic functional groups on said contact lens surface, and then to immerse said contact lens in a solution of the mixture of NVP, PEGMA and photoinitiator, and then remove said contact lens from said solution and expose said contact lens to an ultraviolet light from an ultraviolet device to form a thin film on said contact lens surface. Through the thin film, the contact lens can have good hydrophilicity and anti-fouling properties, so when the patient wear said contact lens, he or she does not feel uncomfortable foreign body sensation, significantly reducing deposit and corneal infection risk.
