Polyamic acid film (PAA) with hollow pore structure was prepared by coagulating the, 4,4'-(hexafluoroisopropylidene) diphthalic anhydride (6FDA) and 3,3'-dihydroxybenzidine(HAB), 6FDA-HAB PAA, solution in a NMP into water bath. We successfully manufactured a porous carbon by carbonizing the coagulated 6FDA-HAB PAA at 1000℃. The carbon material with hollow pore structure showed a high specific surface area of 1668 m2/g.
