摘要：

Polypyrrole (PPy) nanocomposites were synthesized using ferric chloride (FeCl3) as an oxidant by in situ polymerization at room temperature in which reduced graphene oxide- multi-walled carbon nanotubes (RGO-MWCNT) and zinc oxide (ZnO) were used as fillers. RGO-MWCNT and ZnO were synthesized by solution mixing and surfactant assistant precipitation respectively. The RGO-MWCNT-ZnO /PPy nanocomposites were prepared by loading 2, 5, 10 and 20 wt% of RGO-MWCNT:ZnO (1:1) in PPy to measure the electrical conductivity. The PPy nanocomposites were characterized by using FTIR, X-ray diffraction and FESEM. Furthermore, these RGO-MWCNT-ZnO/PPy nanocomposites were investigated to study sensing of ammonia gas at room temperature. The response of 20 wt% loading RGO-MWCNT-ZnO/PPy was observed to be 325% towards 200 ppm of ammonia gas.
