文摘

A new type of organic-inorganic poly(3,4-ethylenedioxythiophene) PEDOT/mesoporous carbon compositewas first synthesized by a simple in situ polymerization of 3,4-ethylenedioxythiophene monomer within themesopores and on the particle surface of CMK-3. The composition, morphology, and structure of the compositewere investigated by thermal analysis, X-ray photoelectron spectroscopy (XPS), electron microscopy, X-raydiffraction, and FT-IR. The composite contained 67.3 wt % of PEDOT and 32.2 wt % of CMK-3 carbonafter the mass of the physically adsorbed water was subtracted. Electron microscopy (SEM and TEM) imagesclearly showed that PEDOT polymer was equally deposited on the surface of CMK-3 nanoparticles. SEMimages also displayed the morphological similarity to the support CMK-3 carbon except for the bigger sizeof the nanoparticles in the composite due to the coverage of polymer PEDOT on the support CMK-3 carbon.FT-IR and XPS analysis showed that PEDOT had been prepared in the resultant composite. The performanceof this interesting composite is being investigated.
