Supercross-linked polymers are widely used as carbon precursor materials due to their abundant carbon sources and low cost. In this paper, a supercross-linked polymer was prepared by the solvothermal method. The supercross-linked polymer as a precursor and the PPyC-800-A was synthesized by activating this with KOH. The microstructure, structure, and electrochemical performances of porous carbon PPyC-800-A were studied at different of temperature and carbon alkali ratio. According to the results, the porous carbon PPyC-800-1:2 is mainly composed of a stack of spherical particles with a high surface area of 1427.03 m2 g− 1, an average pore diameter of 2.32 nm, and a high specific capacitance of 217.7 F g− 1 at a current density of 1.0 A g− 1 in a 6 M KOH electrolyte. It’s retention rate is 97.58% after 5000 constant current charges and discharges. With a specific capacitance decay rate of 21.91 percent, an energy density of 11.96 Wh kg− 1, and a power density of 500.0 W kg− 1, the current density rises from 1.0 A g− 1 to 10.0 A g− 1, exhibiting remarkable electrochemical properties, cycling stability, and energy production performance This study contributes experimental ideas to the field of supercrosslinked polymer-derived carbon materials and energy storage.

본 연구에서는 안정제를 이용하는 반회분식 분산 중합(semi batch dispersion polymerization)공정으로 전도성 고분자인 p-Doped polypyrrole 입자를 제조하였다. 반회분식 분산 중합은 단량체를 monomer starved 조건하에서 연속 주입하여 중합시키는 방법으로써 polyvinylalcohol(PVA)을 안정제로 사용한 경우 평균 50nm, methylcellulose를 안정제로 사용한 경우평균 95nm 정도의 입자 크기를 갖는 dispersion을 제조할 수 있었으며, 이의 입자 크기 및 전도도는 단량체 투입 속도, 개시제 농도와 안정제의 종류, 분자량 및 농도에 따라 변화하였다. 이는 도입 성분중 개시제와 안정제의 역할(친수성 정도, 분자량)에 따라 달라지는 것으로, 이에 따른 물성의 최적점을 찾을 수 있었다.
