Resumen:
Hybrid materials were developed via in situ oxidative polymerization of aniline in presence of 0.5 wt% of nano-/micro-particles. Polymerization was carried out in hydrochloric acid (HCl) medium. Four types of particles were used (aluminum powder 140 mesh, carbon nanotubes and quartz dust in two sizes,400 and 140 mesh). Polyaniline and hybrid materials were characterized by spectroscopic techniques (UV?Vis, FT-IR), thermal analyses (TGA, DSC), morphological studies (FE-SEM); electrical conductivity and wear resistance measurements. The most promising hybrids were obtained by the incorporation of aluminum (140 mesh) or quartz 400 mesh powders. In both cases, electrical conductivity was similar to the one measured for PANI but up to 40% higher wear resistance.
