Grafting Electron Reservoirs at the Periphery ofCore-Shell PEDOT Particles: Towards New Molecular Batteries

摘要

The stable redox activity of nanoscopic materials is a desirable property in the design of molecular-switch devices. One of the present challenges in scientific research is to make high energy-storage systems, cost efficient, lighter and more environmental friendly than the ones based on inorganic systems. For that purpose, conducting polymers are extensively studied since the discovery of the high conductivities reached by polyacetylene. Since the first synthesis of poly(3,4- ethylenedioxythiophene) (PEDOT) in mid 80s, studies showed its high environmental, thermal and electrochemical stabilities, fast switching times, low band gap, high conductivity in doped state. These properties make PEDOT a suitable candidate for applications in batteries, solar cells, sensors, nanoswitches, nanoelectronics, etc
