| Abstract |
Conducting nanocomposites of polypyrrole have been attracted interesting because of their various applications in sensors, memory devices and electromagnetic microwave absorbers. In this study, graphene/polypyrrole nanocomposites were synthesized by in situ method with varying polymerization time to observe how reaction time effects on conductivity of resultant nanocomposites. Experimentally, the conductivity of nanocomposites showed increasing as increasing of reaction time. The morphology was investigated by SEM while chemical components were defined by FT-IR and Raman spectroscopy. The thermal stability of nanocomposites was studied using thermogravimetric analysis (TGA) method. For microwave measurement, nanocomposites were mixed with 20% wt epoxy resin and pressed into a 10cmx10cm mold at different thickness from 1.5mm to 3mm. The vector network analyzer in the range from 8GHz to 12GHz was used to define microwave absorbing performance of nanocomposites. |
