In this work, a new type of advanced 3D macroporous carbon material derived from PIM-1 with a high surface area and electrical conductivity is proposed and anticipated for energy storage applications. PIM-1 (polymer of intrinsic microporosity) is a polymer with a large fractional free-volume with a high surface area of 760 m2/g and chosen as precursor material for carbonization. 3D macroporous PIM-1 films (NPIMs) with continuously interconnected structure were fabricated by applying the nonsolvent-induced phase inversion method. Finally the carbonized NPIMs (cNPIMs) were obtained through direct high temperature pyrolysis of NPIMs without any external activation agent. The cNPIMs presented a very large surface area (2101.1 m2/g) with narrow micropore size distribution (0.75 nm) as shown in Fig. 1. The SEM analysis revealed that cNPIMs also have a unique 3D macroporous structure having both dense skin layer and gradient pore structure, which is expected to grant a smooth and easy ion transfer capability as an electrode material. Consequently, the cNPIM exhibits a high capacitance (405.8 F/g) and long-term stability in aqueous electrolyte. We believe that our approach can provide a variety of new 3D macroporous carbon materials for the application in a electrochemical energy storage.
