将一维（1D）碳质聚吡咯纳米管与二维（2D）石墨烯片结合，采用一锅法构建三维（3D）纳米杂化复合材料。通过调整吡咯与氧化石墨烯的原料配比，可以控制三维纳米结构的形貌。有趣的是，当比例合适时，会形成相互连接的结构。纳米管往往被纳米片覆盖，并且彼此之间相互作用紧密。所得材料的BET （brunauer - emmet - teller）表面积为1173 m2g−1，总孔体积为0.66 cm3−1，平均孔径为3.0 nm。该材料具有较高的比电容和良好的倍率性能，即使在10,000次循环后仍保持94.5%的初始电容。
A one-pot method is introduced to construct three-dimensional (3D) nanohybrid composites by combining one-dimensional (1D) carbonaceous polypyrrole nanotubes with two-dimensional (2D) graphene sheets. The morphologies of 3D nanostructure can be controlled by adjusting the raw material ratio of pyrrole to GO. Interestingly, when the ratio is suitable, the interconnected structured formed. Nanotubes tend to be covered by nanosheets and interacted with each other tightly. The resulting material has a Brunauer-Emmett-Teller (BET) surface area of 1173 m2g−1, a total pore volume of 0.66 cm3g−1, and an average pore diameter of 3.0 nm. And this material used as supercapacitor shows high specific capacitance, good rate capability and still retains 94.5% of the initial capacitance even after 10,000 cycles.
