摘要:
A novel polymeric thin film having a high density, high hardness and high toughness is prepared on the surface of a substrate by plasma polymerization. The gas used to provide the plasma contains a halogenated alkane and/or an alkane and optionally hydrogen and/or a halogen, the atomic ratio of halogen/hydrogen in the gas being from 0.1:1 to 5:1 and the electron temperature of the plasma in the reaction zone being 6,000K or higher and lower than 30,000K. The polymeric thin film obtained is useful on various articles for the purpose of protection, surface hardening, rust-proofing, scratch-proofing, providing a gas barrier, etc. In particular, it is suitable as the protective film for magnetic recording media. %
摘要:
An optical product having a thin film on its surface is obtained by subjecting a mixed gas of oxygen and a hydrocarbon compound having a double bond to plasma polymerization in the presence of the optical product, thereby forming a thin film of a reaction product of said plasma polymerization on the surface of the optical product. This optical product has excellent resistance to fogging due to the adhesion of water drops when used in a gas phase, excellent resistance to the adhesion of air bubbles when used in a liquid phase, high resistance to being stained by oils and fats and an excellent removability of stains due to oils and fats.
