Chemical prepn process of nanometer polyethylene thienyl dioxide

Abstract

The present invention discloses chemical preparation process of nanometer polyethylene thienyl dioxide, and belongs to the field of conducting material preparing technology. The preparation process includes the following steps: compounding 0.5-1.2 mol / L concentration mixed solution of camphor sulfonic acid and ethylene thienyl dioxide, compounding 0.47-2.80 mol / L concentration solution of ferric trichloride, mixing them to initiate polymerization reaction at 0-5 deg.c; centrifugally separating and washing the product with deionized water to neutral, vacuum drying at 50-80 deg.c for 6-24 hr to obtain the navy blue polyethylene thienyl dioxide powder as the product. The preparation process is simple and environment friendly, and the prepared nanometer polyethylene thienyl dioxide has high conductivity, high crystallization degree and other physical characteristics, and possesses latent application in photoelectronic device field.

Description

Problems solved by technology

However, this method requires a hard template with a specific microscopic configuration as an electrode, and after the polymerization is completed, it is necessary to remove the reaction template through a specific solvent, which may cause structural defects in the reaction product, and this method requires specific electrochemical instruments and equipment, which makes it further application is limited

Recently, it has been reported in the literature that one-dimensional nanotube-shaped and rod-shaped PEDOT (J.Jang, M.Chang, M.Yoon, Adv.Mater.2005, 17, 1616; X.Zhang , J.S.Lee, G.S.Lee, D.K.Cha, M.J.Kim, D.J.Yang, S.K.Manohar, Macromolecules.2006, 39, 470), the process of this method is simple, and the requirements for equipment are low, but to obtain the final product requires a large number of Washing with methanol and acetocyanide will cause environmental damage
