Hierarchical Microcellular Microporous Carbon from Polyamic Acid Cryogel and its Electrochemical Capacitance

The obtainment of a high specific surface area (SSA) without disrupting the conductivity of carbon is very challenging. Herein, an as‐synthesized polyamic acid (PAA) derivative dissolved in 1,4‐dioxane solvent was freeze dried to prepare a PAA cryogel, which allowed homogenous shrinkage of the textu...
