Functional groups bearing plasma homo and copolymer layers as adhesion promoters in metal–polymer composites

Functional groups bearing monomers were pulsed plasma polymerised with a degree of retained functional groups of 55-91%. The following functional groups could be produced at a maximum of: 30 OH, 18 NH 2 , and 24 COOH per 100 C atoms. A plasma-initiated radical copolymerisation could also be realised using the functional group bearing monomers as a source of functionalities, olefins as 'chain-extenders' and dienes as 'chemical cross-linkers'. The peel strengths of Al layers on such plasma polymers were correlated to the type and density of functional groups.
