PECVD Plasma Polymerized Thin Films for Surface Engineering

Gas plasma is a versatile, green technology used for surface engineering of materials. When non-polymerizing gases such as oxygen or argon are utilized, surfaces may be cleaned at an atomic level. Polymers can also be modified by rearrangement of the upper most molecular layer and incorporation of chemical functional group. Rather than simply cleaning or modifying the surface of a material, polymerizable gases can be used to create a “new” surface by depositing a highly cross linked nano-coating. Plasma enhanced chemical vapor deposition (PECVD) coatings are permanent and do not affect bulk properties of the base material. Processing under precisely controlled conditions and without use of solvents or reactive chemicals ensures consistent results and an environmentally safe workplace.
