Polymeric films have become more attractive materials for multipurpose applications. In order to adapt them to several kinds of applications, extra functions keeping their bulk characteristics are desired. Modification of PP films through a grafting technique is considered to be one of the main routes to overcome their limitations avoiding coating delamination and without affecting bulk polymer properties. Through this paper the superficial nano-mechanical properties, bulk mechanical properties, and fracture behavior of surface graft copolymerized with acrylic acid PP films are reported.
