The influence of carbon dots (Cdots) in conducting polymers (polypyrrole (PPy) and polyaniline (PANI)) was investigated toward high specific capacitance. Herein, a viable in situ chemical oxidative polymerization method was employed to synthesize the polymer@Cdots composites. The enhancements of specific capacitance and long-term stabilities of PPy@Cdots and PANI@Cdots are due to the synergistic effect of polymers and Cdots. Thus, the Cdots in the composite enhanced more than double the capacitance of original polymers: The specific capacitances of composites were 676 and 529 F/g for PPy@Cdots and PANI@Cdots, respectively, at current density of 1 A/g. This report indicates the remarkable capacitance intension and the desirable durability reinforcement of pseudocapacitors by the easy addition of less-conductive carbon material.

碳点对储能应用中导电聚合物的影响

研究了碳点(Cdots)对导电聚合物(聚吡咯(PPy)和聚苯胺(PANI))对高比电容的影响。在此,采用可行的原位化学氧化聚合方法来合成聚合物Cdots复合材料。PPy @ Cdots和PANI @ Cdots的比电容和长期稳定性的提高归因于聚合物和Cdots的协同效应。因此,复合材料中的Cdots增强了原来聚合物的电容的两倍以上:在1 A / g的电流密度下,PPy @ Cdots和PANI @ Cdots的复合材料的比电容分别为676和529 F / g。该报告表明,通过容易添加导电性较低的碳材料,可显着提高伪电容器的电容强度和耐用性。
