Abstract

Composites based on conducting polymers and two-dimensional (2D) layer structure transition metal oxides are expected to realize the combination of good mechanical properties and excellent capacitance. Here poly(3,4-ethylenedioxythiophene)/molybdenum disulfide (PEDOT/MoS2) intercalated composites were successfully synthesized via in situ polymerization in the presence of ammonium persulfate (APS). The thermal stability, conductivity and capacitance performance are improved significantly with increasing fraction of MoS2. When the content of MoS2 was 45% in weight, the maximum weight loss velocity temperature is 365 °C which is 52 °C higher than that of PEDOT; the specific capacitance was 405 F g−1, about 4 times that of a PEDOT electrode; also the capacity retention was around 90% after 1000 cycles. This study provides a facile preparation method of organic/inorganic nanocomposites with enhanced electrochemical capacitance performance.
