Modern corrosion protective coatings for aluminum substrate are expected to present both strong barrier and self-healing properties. To fulfill these requirements, coating material is commonly comprised of several layers where at least one layer can be a highly cross-linked plasma polymerized film (PPF) deposited by plasma-enhanced chemical vapor deposition (PECVD). Depending on deposition parameters, this PPF might contain a certain amount of surface free radicals that can serve as initiation sites for conventional radical polymerization.The aim of present work is to develop new multilayer coating materials using an isopropanol-based PPF from which free radicals were generated. Prior to the polymerization of the second polymeric layer, the optimal conditions to generate maximum density of free radicals on the PPF surface were determined using nitrogen monoxide (NO) as labeling agent. Successful polymerization of EHA was then carried out on the surface and optimized.
