Abstract

Article history: The hybrid composite of poly(3,4-ethylenedioxythiophene) (PEDOT) and halloysite nanotubes (HNTs) Received 28 April 2017 was synthesized by a two-step process. First, poly(sodium styrene sulfonate) (PSSNa) was grafted onto Received in revised form 21 August 2017 HNTs via surface initiated atom transfer radical polymerization. Then with the HNTs-g-PSS as a template Accepted 24 August 2017 and the grafted PSS chains as the counterion dopant, PEDOT was precipitated onto the template via Available online 4 September 2017 in situ oxidization polymerization of EDOT to form HNTs@PEDOT hybrid composites. The conductivity of HNTs@PEDOT can reach up to 9.35 S/cm with the content of 40% HNTs-g-PSS, which increased almost Keywords: 78 times than that of pure PEDOT (about 0.12 S/cm) prepared at the similar condition. Further treated Conductive polymer with p-toluenesulfonic acid (TsOH) as external dopant, the conductivity of HNTs@PEDOT increased to Halloysite nanotubes 24.3 S/cm. The electrochemical properties of the composites were investigated with cyclic voltammetry, PEDOT galvanostatic charge-discharge and electrochemical impedance spectroscopy with three-electrode cell HNTs@PEDOT composites configuration. The results showed that the capacitance of HNTs@PEDOT composite increased 55% than that of pure PEDOT. © 2017 Elsevier B.V. All rights reserved. 1.
