Fabrication of PEDOT/PSS-ZnO nanowire by self-assembly method under vacuum condition

Poly(3,4-ethylenedioxythiophene) (PEDOT) has at- tracted much attention due to its high conductivity, excel- lent environmental stability and chemical processabil- ity[1,2]. PEDOT/PSS dispersion is a water-soluble system using poly(styrene sulfonic acid) (PSS) as the doping counterion during polymerization. The inclusion of PSS results in better solubility and processability to the PE- DOT/PSS aqueous dispersion[3, 4]. Recently, synthesis of one-dimensional (1D) multifunc- tional co…

Flexible organic light-emitting diodes with poly-3, 4-ethylenedioxythiophene as transparent anode

The flexible oragnic light-emitting diodes (OLEDs) fabricatedon poly-3, 4-ethylenedioxythiophene/polystyrenesulfonate (PEDOT/PSS) coated substrates were demonstrated. How the fabricating processes and the device structure will affect the device performance was studied and the atomic force microscopy was employed to analyze the mophorlogy of the conducting polymer anode. Under optimized conditions, flexible OLEDs with PEDOT anode showed the brightness up to 2760 cd/m² and maximum external quantum efficiency of 1.4%. These data are comparable to those of conventional flexible OLEDs with ITO anode.

高电导率、对空气和水高度稳定、可溶液加工处理、成本低一直是导电高分子研究领域研究人员追求的目标.经过20多年的研究发现聚噻吩的衍生物聚（二氧乙撑噻吩）与聚对苯乙烯磺酸（简写PEDOT/PSS）可以在水中形成稳定的悬浮液,涂布后可以形成高性能的导电膜,电导率可达103 S cm-1（掺杂适量的极性有机溶剂）,且对热、光、水、空气均具有良好的稳定性,可见光透过率良好,与其它助剂一起可以实现更优良的性能,因此在众多工业领域取得了广泛研究和应用.本文将介绍PEDOT/PSS的历史、制备方法、复合材料以及在抗静电、电致变色、有机发光二极管、太阳能电池等方面的应用.     

喷涂制备聚合物太阳能电池阳极缓冲层中所用溶液浓度对器件性能影响机理

以在空气中结构稳定和电导率高等特点的PEDOT:PSS为样本,针对溶液浓度与喷涂薄膜成膜特性及在此基础上制备的P3HT:PCBM体异质结聚合物太阳能电池器件,进行了表征和分析.结果表明:器件的电流密度和效率随喷涂溶液浓度增大而提高的原因是喷涂溶液浓度的增加导致所制得薄膜的表面粗糙度增大,从而增大了与体异质结的接触面积,提高了载流子的传输和收集效率;在采用浓度为66.67%的PEDOT:PSS水溶液喷涂制备的缓冲层基础上制备的P3HT:PCBM体异质结聚合物太阳能电池,短路电流达到12.08mA/cm2.     

PEDOT膜修饰电极对对苯二酚及邻苯二酚的电催化研究

研究了电化学聚合制备的聚乙撑二氧噻吩(PEDOT)膜修饰电极对对苯二酚和邻苯二酚的电催化.结果表明PEDOT膜修饰电极对对苯二酚和邻苯二酚均有很强的电催化作用,它们可能来自PEDOT对二羟基酚类的吸附作用.研究和分析了影响膜催化性能的2个因素:聚合电位、掺杂离子.PEDOT膜中掺杂的阴离子对催化性能有重要的影响,而膜聚合电位对PEDOT膜修饰电极行为的影响则是由于膜电阻随膜聚合电位的变化所引起的.     

Electrochemical characterization of the Pt /PEDOT electrode in DMFC

Poly-(3, 4-ethylenedioxythiophene) (PEDOT) was applied in making electrodes and gas diffusion layer for direct methanol fuel cells (DMFC). Electrochemical characterizations of Pt/PEDOT electrodes, made by two different methods, were investigated by cyclic voltammetry, methanol oxidation tests and DMFC performance. The platinum particle structure in PEDOT/PSS (poly?styrene sulfonic acid) films was investigated by SEM and TEM. Our research work showed that PEDOT influenced the catalytic activity behavior in three different ways when it was applied to the anode, cathode and the gas diffusion layer. The DMFC performance agreed with the cyclic voltammetry and methanol oxidation test results.
