Microwave plasma modification of surface properties in organic polymers

摘要

The invention provides a method of improving the properties of an organic or inorganic substrate so as to render the same more susceptible to coating treatment or to impart improved adhesion characteristics thereto. The method comprises the steps of providing a solid substrate, elevating the temperature of the substrate to at least 40 DEG C., and subjecting the substrate to a cold plasma, and if desired, coating the substrate with a coating material after the substrate has been heated. There is also provided a method of modifying the surface properties of an aramid polymer. The method comprises providing an aramid polymer product, generating a cold plasma, and exposing the aramid polymer to the plasma whereby the surface properties of the aramid polymer are enhanced.
