Nontemplating Porous Carbon Material from Polyphosphamide Resin for Supercapacitors
Summary: The nontemplating preparation of porous carbon materials by using specially designed polymer precursors for supercapacitor is attracting considerable research attention because of the more controllable frame structure and easier processes than templating methods. Herein, a deliberately desi...

Summary: The nontemplating preparation of porous carbon materials by using specially designed polymer precursors for supercapacitor is attracting considerable research attention because of the more controllable frame structure and easier processes than templating methods.

The as-obtained porous carbon material has a specific surface area of 2,620 m2 g−1, high porosity of 1.49 cm3 g−1, and well-distributed micro/mesoporous carbon structure.
