The aim of the study is to activate inert PET surface in order to introduce the carboxyl groups and to obtain its hydrophilic character. Two advanced and environmentally friendly techniques were used for these purposes: i) oxygen plasma activation; ii) enzymatic treatment by cutinase. Differently treated PET foils were studied in terms of carboxylic group content (non-aqueous potentiometric titrations, XPS) and hydrophobic/hydrophilic character (goniometry). Moreover, the influence of both… Expand
