In this study, SLA (Stereolithography) method was used to fabricate three-dimensional micro-structures. A soft polymer
such as PDMS (Polydimethylsiloxane) was used as a mold to duplicate the pattern of the micro-structures. Polyaniline
(PANI) films with micro-structures on the surface using PDMS molds were prepared as electrodes of supercapacitor. A specific
capacitance 391 F/g at a of 1 A/g was measured for the PANI micro-structures, while the specific capacitance of PANI plane
is 304 F/g. To achieve higher energy storage, laser interference lithography was employed to fabricate nano-structures on the
micro-structures. The specific capacitance 487 F/g was obtained for the micro/nano hierarchical structures due to increase in
the surface of PANI electrodes.
