Green synthesis of Co_3O_4/polyaniline nanocomposites: Structural, morphological and conductivity studies

摘要

Polyaniline (PANI)/Cobalt oxide (Co_3O_4) hybrid nanocomposites (NCs) were synthesized by means of in-situ polymerization using Cobalt nitrate as metal precursor, Polyaniline as polymerizing agent and Aloe-Vera (A.V.) gel as a fuel. The prepared nano composites were characterized by different characterization techniques such as Powder XRD, SEM and TEM. The electrical properties of PANI/Co_3O_4 hybrid NCs are very unique in comparison to the pure phases, PANI and Co_3O_4 nanoparticles (NPs), which were ascribed to the interaction between the PANI and Co_3O_4 nano particles. DC conductivity is observed to be enhanced as the Co_3O_4 NPs concentration increased from 10 to 50 wt% in the hybrid NCs at the different temperature. From the obtained measurements and data, the synthesized hybrid nano composites may be used in electronic device applications such as LED devices, solar cells and optical devices.
