Plasma Polymerization
Term: Plasma Polymerization
Category: Coating Method
Definition: Plasma polymerization modifies and coats surfaces by introducing gaseous monomers into a plasma discharge, typically under low-pressure or atmospheric conditions. A high-energy environment generates chemical species that act as reactants (e.g., radicals, ions, or electrons), which lead to the direct formation of polymer on the substrate’s surface.
The final product is a very homogeneous, pinhole-free, and strongly bonded layer of polymer with customizable chemical, hydrophilic, and biocompatible properties or barrier functions.
Plasma polymer films differ from standard polymers in that they are more likely to be more highly crosslinked and chemically more stable, and therefore, can be used in many demanding biomedical and industrial applications.
