The poly(2,5-dimethoxyaniline) (PDMA) were synthesized through interfacial polymerization method using three various organic solvent/water reaction systems. As comparison with conventional chemical polymerized PDMA, the interfacial polymerization can produce uniform nanoparticular PDMA, especially for using high density (higher than water) solvent as organic phase. The capacitive performances of interfacial polymerized PDMA can be benefited from its uniform morphologies and loose packing structure. The specific capacitance of interfacial polymerized PDMA using carbon tetrachloride is 194 Fg(-1) at current density of 50 mA cm(-2), which has 59% enhancement over 122 Fg(-1) of conventional PDMA at the same current density. The energy density of interfacial polymerized PDMA is 39 Wh kg(-1) at current density of 5 mA cm(-2) and the power density is 28,421 W kg(-1) at current density of 50 mA cm(-2). The energy density has improvement in different extent as comparison with that of conventional PDMA. The enhanced capacitive performances can be attributed to the increased ionic conductivity induced by the loose molecular packing structure and uniform morphology produced by the interfacial polymerization process.
