Abstract

This contribution is aimed to show the Mayn results recently obtained by our group in the framework of the COST Plasma and Ion Surface Engineering (PISE) ACTION 515. Two plasma-modification processes are briefly described, namely: the deposition of thin SiO_xC_yH_z gas-barrier coatings on polyethylenetherephtalate and the modification of polyethylene aimed to the surface-immobilization of anti-thrombotic molecules. Particular attention is devoted to describe how the two processes can be controlled by means of plasma- and surface-diagnostic techniques.
