A plasma technology that is rapidly emerging into mainstream industry is that of plasma coating/thin film deposition.
Typically, a high level of polymerisation is achieved by application of plasma to monomeric gases and vapours.
Thus, a dense, tightly knit and three-dimensionally connected film can be formed which is thermally stable, chemically very resistant and mechanically robust.
Such films are deposited conformally on even the most intricate of surfaces and at room temperature which ensures a low thermal burden on the substrate.
Plasmas are therefore ideal for the coating of delicate and heat sensitive, as well as robust materials. Plasma coatings are free of micropores even with thin layers (e.g. 0.1 µm).
The optical properties, e.g. colour, of the coating can often be customised and plasma coatings adhere well to even non-polar materials, e.g. polyethylene, as well as steel (e.g. anti-corrosion films on metal reflectors), ceramics, semiconductors, textiles etc.
