Polymeric nanocomposites consist of nanoparticles imbedded in organic polymers, comprising a new class of materials. The combination of conducting nanoparticles and conducting polymers, described as hybrid electrically conducting nanocomposites, is a new emerging field. These materials may exhibit unprecedented properties, attractive for both the industry and academia. There is a variety of applications for conductive nanocomposites, i.e., sensors, actuators, touch screens, etc. The combination of conductive polymers with conductive carbon nanotubes has already shown some synergistic properties. The goal of the present review is to summarize the literature reporting work done on combining polyaniline (PANI), an electrically conductive polymer, with carbon nanotubes (CNT) including the authors' work.
