摘要: 采用液相共混法，以酚醛树脂和氧化石墨为原料，得到氧化石墨烯/酚醛树脂复合材料，再通过高温碳化和活化工艺，制备出石墨烯/活性炭复合材料.采用循环伏安和恒流充放电测试表征其电化学电容性能，结果表明：该复合材料在0.5 A·g^-1的电流密度下比电容高达197 F·g^-1，当电流密度增加到10 A·g^-1时，比电容为163 F·g^-1，电流增加20倍，电容保持率为83%，在0.5 A·g^-1的电流密度下循环1000次，未见容量有衰减，电容保持率为100%.这表明该复合材料具有优良的电容性能.

Abstract: The graphene/phenolic resin composites were prepared by liquid phase blending method using phenolic resin and graphene oxide as raw materials, and then graphene/activated carbon composites were prepared by high temperature carbonization and activation process. Cyclic voltammetry and constant current charge-discharge tests were used to characterize the electrochemical capacitance. The results showed that the composite had a specific capacitance of 197 F·g-1 at a current density of 0.5 A·g-1, and the current density increased to 10 A·g-1, the specific capacitance was 163 F·g-1, the current was increased by 20 times, the capacitance retention rate was 83%, and the cycle was repeated 1000 times at a current density of 0.5 A·g-1, and no capacity was attenuated, the capacity retention rate was 100%, which indicated that the composite material had excellent capacitance properties.
