Graphene oxide can help PEDOT conduct electricity, to enable efficient plastic supercapacitors

PEDOT, short for poly(3,4-ethylenedioxythiophene), is a flexible, transparent film often applied to the surfaces of photographic films and electronic components to protect them from static electricity. It is also found in touch screens, organic solar cells and electrochromic devices, such as smart windows. However, PEDOT’s potential for energy storage has been limited because commercially available PEDOT materials lack the electrical conductivity and surface area needed to hold large amounts of energy.
