▎ 摘  要

Graphene oxides (GO) prepared from graphite was used in the preparation of three-dimensional (3D) super porous graphene aerogel (GA) by chemical reduction of GOs with L-Ascorbic acid (L-AA) via freeze drying. Then, the conductive polymers such as poly(aniline) (PANi), and poly(pyrrole) (PPy) within the superpores of 3D GA were prepared as GA/PANi and GA/PPy interpenetrating composites (IPC). The electrical conductivity of GA was measured as 4.17 x 10(-2) +/- 6.40 x 10(-3) S/cm, whereas the electrical conductivity of GA/PANi was decreased to a half value and increased 3-fold for GA/PPy IPC. Moreover, bare GA, GA/PANi, and GA/PPy IPCs were exposed to CO2 gas at room temperature, 20 degrees C +/- 2 degrees C for potential sensor application by comparing the change in their electrical conductivities. Interestingly, it was found that the electrical conductivity of GA/PANi IPC composites was decreased 4,000 times upon 60 min CO2 gas exposure at ambient temperature and pressure suggesting potential CO2 gas sensor application of the prepared materials.
