通过一步循环伏安法在水溶液中制备了具有环状、箭头状和泡状微结构的聚（4-苯乙烯磺酸盐）掺杂聚（3,4-乙烯二氧噻吩）（PEDOT/PSS）薄膜。研究了施加电位和表面活性剂/掺杂剂pss对膜形貌的影响，并提出了气泡模板机理。结果证实了PSS在PEDOT薄膜中的良好掺杂。进一步研究了微结构PEDOT/PSS薄膜的电化学性能和电导率。在制造微器件和微传感器方面具有潜在应用的类似制备可以扩展到其他微结构导电聚合物。(c) 2006 Elsevier B.V.版权所有
Poly(4-styrene sulfonate)-doped poly(3,4-ethylenedioxythiophene) (PEDOT/PSS) films with ring-, arrow-, and bubble-like microstructures have been electrochemically generated simply by a one-step cyclic voltammetry in an aqueous media. Influences of applied potentials and surfactant/dopant-PSS on morphology of the resulting film were investigated, and a gas bubble template mechanism has been proposed. The result confirmed a well-doping of PSS in the PEDOT film. Electrochemical property and conductivity of the micro-structured PEDOT/PSS film were investigated further. Similar preparation with potential applications in fabrication of microdevices and micro-sensors can be extended to other micro-structured conducting polymers. (c) 2006 Elsevier B.V.
