Thin film composites of nanocarbons-polyaniline obtained by plasma polymerization technique

We report a cheap and reliable method to produce thin films nanocomposites with a novel method of plasma polymerization having coupled an atomizer head. In particular, Polyaniline-nanocarbons (PPAniNC)were deposited on silicon substrate aiming at nanocomposites with functional gradient properties, proton exchange membranes with catalytic effect, electronic transport with charge accumulation and electromagnetic shielding. Combining the aniline with dispersed nanocarbons (NC)and polymerized in plasma is one of the alternatives do match these requirements. The insertion of the nanometric carbons into polyaniline films has been accomplished by the simultaneous injection in the plasma reactor. The films were characterized by FT-IR, Raman, AFM, and electrical measurements. The measurements show specific features, which demonstrate that the composites consisting of nano-sized carbon particles functionalized by chemical bonded between the polymer chains
