Co to jest Plasma Polymerization?

Plasma polimization is a dry, solvent- free process that use low-pressure or amberyc-pressure plasma to deposit thin polymer films onto solid substrates. In this technique, a precursor gas - often an organic monomer or a mixture of gases - is propéd into a plasma reactor. These electrical field ionizes the gas, creating a mixture of controls, ions, radicals, and excited species.
