Radiation‐Grafted Polymerization from a Gas Phase to Form Polymeric Layers on Metal Surfaces

Abstract

Summary: Experimentally it is shown that, under irradiation in an atmosphere of non‐saturated vinylidene chloride vapors, a polymeric layer is formed on the surface of oxidized titanium samples. The thickness of this layer increases with the increase of thickness of the oxide film. Such a dependence corresponds to the current understanding of the mechanism of formation and migration of the active excited centers that initiate grafted polymerization.Wide range XPS spectra of oxidized titanium samples after PVDC grafting from a gas phase.imageWide range XPS spectra of oxidized titanium samples after PVDC grafting from a gas phase.
