摘要: 分级多孔材料由于在超级电容器、吸附、催化和生物医学等领域的潜在应用而备受关注。因此，本章主要是通过微乳液聚合的方法，先预碳化合成碳材料，再通过化学活化的方法实现分级碳泡沫材料的制备。研究表明，在微乳液体系中，酸性条件下合成出来的碳材料与KOH活化比为1:3时获得的分级碳泡沫表现出较大的比表面积(1133.4 m2/g)以及较高的孔体积(0.96 cm3/g)。此外，在三电极体系、6 M KOH的电解液下，HCF-HCl-2在1 A/g的电流密度下表现出最大的比电容为214.8 F/g。并且在1 A/g的电流密度下循环1000圈后仍旧保持96.6%的比容量。说明了分级多孔碳电极材料是一种有前景的储能材料。
Abstract: Hiearchical porous materials have attracted much attention due to their potential applications in the fields of supercapacitors, adsorption, catalysis and biomedicine. Therefore, the carbon materials were synthesized by microemulsion polymerization and precar-bonization in this work. Then the hierarchical carbon foam material was prepared by chemical ac-tivation. The results show that in the microemulsion system, the carbon material synthesized under acidic conditions and the carbon foam obtained with the activation ratio of 1:3 to KOH showed a larger specific surface area (1133.4 m2/g) and a higher pore volume (0.96 cm3/g). In addition, the maximum specific capacitance of HCF-HCl-2 is 214.8 F/g at 1 A/g current density in a three-electrode system with 6 M KOH electrolyte. And the specific capacity remains 96.6% after 1000 cycles at 1 A/g current density. The results show that the hiearchical porous carbon electrode material is a promising energy storage material.
