Synthesis of highly sensitive ammonia gas sensor of polyaniline/graphene nanoribbon/indium oxide composite at room temperature

Indium trioxide (In2O3) nanoparticles prepared using a solvothermal reaction were coated on the surface of graphene nanoribbon (GNR) to serve as a core for the manufacture of polyaniline (PANI)/In2O3/GNR ternary nanocomposites produced using in situ chemical oxidative polymerization. The gas-sensing properties of nanocomposites were evaluated by a homemade dynamic test system at room temperature, which was equipped with a real-time resistance...
