Surface modification of polymeric films is a way to obtain final products with high performance for manyspecific and ad hoc tailored applications, e.g. in functional packaging, tissue engineering or (bio)sensing.The present work reports, for the first time, on the design and development of surface modified ethylene–acrylic acid copolymer (EAA) films with polyaniline (PANI), with the aim of inducing electrical conductivityand potentially enable the electronic control of a range of physical and chemical properties of the filmsurface, via a new ‘‘grafting from’’ approach. In particular, we demonstrate that PANI was successfullypolymerized and covalently grafted onto flexible EAA substrates, previously activated. The final hybridmaterials and the corresponding intermediates were fully characterized via FTIR, XPS, SEM–EDAX,mechanical and electrical tests. The mechanical properties of the films are not detrimentally affectedby each treatment step, while a significant increase in electrical conductivity was achieved for the newhybrid materials.
