摘要

采用单步氧化聚合法制备了高稳定性的聚（3,4-乙烯二氧噻吩）（PEDOT）和PEDOT/银胶体分散体。以水溶性聚合物聚n -乙烯基吡罗烷酮和聚乙烯醇作为位阻稳定剂，硝酸铁和硝酸银作为氧化剂。利用紫外可见光谱和拉曼光谱证实了PEDOT长共轭链的形成。通过扫描电镜、透射电镜和紫外可见光谱验证了银纳米颗粒在PEDOT中的掺入。研究了稳定剂和氧化剂对PEDOT颗粒尺寸、形貌、导电性和润湿性的影响。对PEDOT胶体滴铸成膜的AFM分析显示，薄膜具有不同的形貌。聚乙烯醇和硝酸铁（III）制备的PEDOT薄膜电导率最高，为0.95±0.07 S cm−1。

Conductive films cast from highly stable PEDOT and PEDOT/silver colloidal dispersions

Highly stable poly(3,4-ethylenedioxythiophene) (PEDOT) and PEDOT/silver colloidal dispersions were synthesized through single-step oxidative polymerization. Water-soluble polymers, poly(N-vinyl pyrrolidone) and poly(vinyl alcohol), were used as steric stabilizers and iron(III) nitrate and silver nitrate were used as oxidants. The formation of PEDOT long conjugated chains was confirmed using UV–visible and Raman spectroscopies. The incorporation of silver nanoparticles into PEDOT was verified with scanning and transmission electron microscopies and UV–visible spectroscopy. The effect of stabilizer and oxidant types on PEDOT particles' size, morphology, conductivity and wettability were studied. The AFM analysis of drop-cast films of the PEDOT colloids reveals homogeneous films with varied topographies. The PEDOT films prepared with poly(vinyl alcohol) and iron(III) nitrate showed the highest electrical conductivity of 0.95 ± 0.07 S cm⁻¹.

期刊介绍： The aim of this international journal is to analyse and publicise the progress and current state of knowledge in the field of organic coatings and related materials. The Editors and the Editorial Board members will solicit both review and research papers from academic and industrial scientists who are actively engaged in research and development or, in the case of review papers, have extensive experience in the subject to be reviewed. Unsolicited manuscripts will be accepted if they meet the journal''s requirements. The journal publishes papers dealing with such subjects as: • Chemical, physical and technological properties of organic coatings and related materials • Problems and methods of preparation, manufacture and application of these materials • Performance, testing and analysis.
