Properties of ordered conducting polymer ultrathin film
摘要
Abstract
A Langmuir-Blodgett (LB) inducing method was firstly used to prepare single layer and multilayer conducting composite PEDOT-PSS film. The film-forming ability of ionization ODA and ODA-SA monolayer spread on PEDOT-PSS nanoparticles subphase and the behavior of ODA/PEDOT-PSS assembly particles on pure water were firstly investigated. The results indicated that PEDOT-PSS nanoparaticles in subphase packed the ionization monolayer to form stable complex Langmuir film was formed at air/water interface. It was found that the best film-forming conditions for composite film were as follows: distinct interface was formed between ODA and PEDOT-PSS layer and single layer thickness of PEDOT-PSS was about 23 nm, which was well in accordance with the size of PEDOT-PSS nanoparticles. Different structures were designed to test the conductive ability of these composite films and a varible range hopping (VRH) model was used to explain the film conductive mechanism. The results indicated that a 3D-VRH model explained well of transferring of charge carrier in multilayer film.关键词
