Comparative study of carbon-based nano-fillers/polyaniline hybrids reinforced polymer composites

Graphene oxide(GO), multi-walled carbon-nanotube(MWCNT) and fullerene(C60) were selected to make the carbon/PANI hybrids reinforced polymer composites. The doping action, dispersion state, thermal abilities, electrical conductivities, thermal conductivities and mechanical properties were characterized and compared. The doping action in three systems are different and the PANI/Carbon hybrids appear as a uniform network structure. GO/PANI and C60/PANI sample have higher decomposition temperature and lower thermal loss, while the MWCNT/PANI hybrids reinforced composites have lower decomposition temperature and thermal loss, which means MWCNT is not effective to improve the thermal stability of the PANI composites. The electrical conductivity of MWCNT-PANI/PDVB agrees well with the law of Landauer model, and Voigt-Reuss model can explain the modulus’change of the composites.
