Popis: |
Graphene/Polyvinylidene fluoride (PVDF) conductive composite materials were prepared by co-solvent method. GO were stably dispersed in H2O/N, N-dimethylformamide (DMF) (1∶9, volume ratio) medium. After sonication, a clear stable brown solution was prepared without any visible aggregation. Changes in the internal structure and crystallization properties is demonstrated of the graphene/PVDF composites by scanning electron microscopy (SEM) and differential scanning calorimetry discussion(DSC).It was shown that in the 1:9 mixed solvent of H2O/DMF can improve GO concentration which increased 2.98 times and can form a homogeneous stable solution. The resistance decreases with temperature, indicating an NTC behavior and the room-temperature resistivity downward trend during the thermal cycles. |
