Abstract

The polyvinylidene fluoride film was coating with proteins to increase the biocompatibility and to create new sensitive surface to environment. The two steps procedure to obtain such surfaces consists in the surface activation by CO2, N2 or N2/H2 plasmas leading to the attachment of short carboxyl or amino groups then in the second step, the proteins (triglycine and protein A) were physiadsorbed or chemically grafted onto the carboxyl or amino-surface. These new surfaces have been characterized by wettability measurements, ATR-FT-IR, and SEM/EDX methods. The results proved that PVDF is a good substrate for proteins coating which further lead to increased functionality and biocompatibility of the hydrophobic surface..
