In-situ polymerization was used to create Polyaniline (PANI)/Cobalt oxide (Co3O4) hybrid nanostructures (NSs) utilizing Cobalt nitrate as a metal precursor, Polyaniline as a polymerizing agent, and Aloe-Vera (A.V.) gel as an organic fuel. In contrast to the unadulterated segments, PANI and Co3O4nanoparticles (NPs), due to communication among the PANI and the Co3O4 nano particles, the electrical investigations of PANI/Co3O4 hybrid NCs are rather distinct. The results of the gas sensing investigations show that the constructed NCs have an excellent reaction to gas leaking. As the Co3O4 NPs concentration increases from 10% to 50% wt%, AC and DC conductivity in the hybrid NCs increases from 1 x10-5 to 5 x 10-5 (S/cm)-1 at ambient temperature. Based on the results of the measurements and data collected, the synthesized hybrid nanocomposites might be employed in optoelectronic device applications and it’s a semiconducting material.
