ABSTRACT:
An an improved process for surface modification of solid substrates, such as polymers and carbon-based materials, is disclosed. The preferred process comprises three steps: a first activation step wherein reactive hydrogen groups are formed in a surface layer of a polymeric or carbon-based material; a second silylation step wherein the reactive hydrogen groups are reacted with a silylating agent to form silicon-containing groups; and a third stabilization step wherein an upper portion of the activated, silylated layer is oxidatively converted to a silicon and oxygen enriched surface layer. The process can be performed using materials not having pre-existing reactive hydrogen groups or precursor groups. Modified materials according to the present invention have improved properties, such as erosion resistance and oxygen and water barrier properties, and are potentially useful in numerous industries, such as aerospace and packaging.
