Nanocomposite electrolytes in Oxymethylene-linked Polyoxyethylene Multi-block Polymer: FT-IR, Spectral transmittance and Conductivity studies
首发时间:2006-03-29
Abstract:Oxymethylene-linked polyoxyethylene multi-block polymer was synthesized by condensing dichloromethane with poly (ethylene glycol) (PEG) of different molecular weight in the presence of potassium hydroxide power. The ionic conductivity of the block-polymer prepared with the PEG mixture of different average molecular weight, PEG400 and PEG600, is higher than it of which prepared with only a kind of molecular weight of polyethylene glycol (PEG), such as PEG400 or PEG600. There is one order of magnitude increase in the ionic conductivity at the room temperature. The complexation has been confirmed using FT-IR spectral studies. Ionic conductivity of gel composite electrolyte was studied with temperature. The gel polymer electrolyte systems based on block-polymer-nanoparticles appear very promising for all-solid-state complementary electrochromic devices because of high transmittance in the visible light region.
