Abstract
Various factors of the influence of carbon matrices on the textural, structural, and electrochemical properties of nanocomposites based on highly dispersed carbon black after the thermal-oxidative action of steam are considered. The results of the measurements of the electrical resistance of nanocomposites with coke-pitch and pyrocarbon matrices and the testing of these materials by cyclic voltammetry in a two-electrode Swagelok cell with an aqueous electrolyte are given. An optimal ratio between a pyrocarbon matrix and carbon black, at which the specific capacity of the electrode reached a maximum and was comparable with the values for active carbon–based electrodes widely used in world practice, was established.

碳基质对高分散炭黑纳米复合材料性能的影响
摘要
考虑了在蒸汽的热氧化作用后,碳基质对基于高度分散的炭黑的纳米复合材料的组织,结构和电化学性能的影响的各种因素。给出了用焦炭沥青和热碳基体测量纳米复合材料电阻的结果,以及在带有水电解质的两电极Swagelok电池中通过循环伏安法测试这些材料的结果。确定了焦碳基质与炭黑之间的最佳比例,在该比例下,电极的比容量达到最大值,并且与世界范围内广泛使用的活性炭基电极的值相当。
