Conducting polymers are attractive as they possess electronic, magnetic, and optical properties similar to metals while retaining the flexibility and processibility of conventional polymers. Compared with other conducting polymers, polyaniline (PANI) is unique due to its relative environmental stability and interesting redox properties. So far, polyaniline (PANI) nanostructures (nanofibers, nanosheets and nanoparticles) have been synthesized by different strategies for various applications. The classical chemical synthesis of polyaniline uses aniline, an oxidant and a strong mineral acid dopant. In the past years, a variety of chemical methods were reported, such as hard or soft template synthesis, nanofiber seeding and electrochemical polymerization. In order to restrain the agglomeration phenomenon interfacial polymerization is employed to synthesize polyaniline nanofibers because it is not dependent on any template or emulsifier.In this work, by interfacial polymerization we have successfully synthesized polyaniline nanofibers with diameters under 100 nm, which are among the smallest reported for polyaniline nanofibers without using a template. The effect of synthesis conditions such as [An], [APS], solvent, temperature and reaction time on the morphologies of polyaniline nanofibers was investigated, and the mechanism controlling the growth of polyaniline nanofibers was discussed. Conductive polymer matrix composites were prepared by using polyaniline nanofibers as conductive components. The resistance welding of polycarbonate (PC) was investigated using the conductive polymer matrix composites as a heating resistor.
