Green Precursors and Soft Templating for Printing Porous Carbon‐Based Micro‐supercapacitors

A combination of soft lithographic printing and soft templating has been used to fabricate high‐resolution interdigitated micro‐supercapacitors (MSC). Surfactant‐assisted self‐assembly produces high surface area ordered mesoporous carbons (490 m(2) g(−1)). For the first time, such precursors have be...

Sumario:A combination of soft lithographic printing and soft templating has been used to fabricate high‐resolution interdigitated micro‐supercapacitors (MSC). Surfactant‐assisted self‐assembly produces high surface area ordered mesoporous carbons (490 m(2) g(−1)). For the first time, such precursors have been printed by nano‐imprint lithography as microdevices with a line width of only 250 nm and a spacing of only 1 μm. The devices are crack‐free with low specific resistance (1.2×10(−5) Ωm) and show good device capacitance up to 0.21 F cm(−3).
