Poly(3,4-ethylenedioxythiophene) and its derivatives provide an excellent platform as electrode materials for supercapacitors due to their superior stability and conductivity. In this study, a poly(2,3-dihydrothieno[3,4- b ][1,4]dioxin-2-yl)methanol (PEDOT-MeOH) porous nanonet (PEDOT-MeOH-PNN), PEDOT-MeOH hollow nanotube array (PEDOT-MeOH-HNA) and PEDOT-MeOH-PNN coated PEDOT-MeOH-HNA (PEDOT-MeOH-PNN@PEDOT-MeOH-HNA) are successfully fabricated using a template-free electrodeposition of (2,3-dihydrothieno[3,4- b ][1,4]dioxin-2-yl)methanol monomer. These three nanostructures were studied by Fourier transform infrared spectrum and Raman spectrum, scanning electron microscopy, thermal analysis and electrochemical methods, respectively. PEDOT-MeOH-PNN@PEDOT-MeOH-HNA has a specific capacitance of 40.5 mF cm −2 at 40 mV s −1 , which is higher than PEDOT-MeOH-PNN (21.6 mF cm −2 ) and PEDOT-MeOH-HNA (35.5 mF cm −2 ). Moreover, the PEDOT-MeOH-...
