Synthesis and semiconductor characteristics of Poly(2-methoxy, 5-octoxy)1,4-phenylenevinylene-carbon nanotube Composites

摘要

Poly[(2-methoxy, 5-octoxy)1,4-phenylenevinylene-carbon nanotube composites (MOPPV-CNTs) were synthetized by In-situ polymerization in the paper. The molecular structure and surface morphology of the nanocomposites were characterized by the TEM. The TEM results showed that the MOPPV coated on the CNTs forming Core-shell nanowires structure composite. The wavelength of UV-absorption spectra of the composites exhibited a blue shift caused by the functionalized MWCNTs. the energy gap of the composites were increased. The band structures of the composite were determined by using cyclic voltammetry, the result shown that the HOMO energy and the LUMO energy increased with the concentration of CNTS. The increase of LUMO energy would benefit for balance of the carries injection when the composites used in the optoelectronic devices.
