在含有绿色非离子糖基表面活性剂N-十二烷基-β-d-麦芽糖苷（DM）的水溶液中，以较低的单体浓度（0.005- 0.01 mol L-1），通过直接阳极氧化法制备了聚3，4-乙撑二氧噻吩（PEDOT）膜。DM通过羟基与EDOT单体之间的适度相互作用导致单体氧化起始时间的降低。不同的表面活性剂，如阴离子十二烷基苯磺酸钠（SDBS），非离子Triton X-100（TX 100），也进行了测试比较。作为形成的PEDOT薄膜，其特征在于电化学和光谱使用FTIR和紫外-可见光技术。在水-DM胶束溶液中可以合成具有良好热稳定性和电导率为26.2Scm− 1的PEDOT纳米材料，这可以通过扫描电子显微镜（SEM）的结果来证明。由水-DM介质制备的PEDOT具有良好的生物相容性，可用于生物传感器。
Poly(3,4-ethylenedioxythiophene) (PEDOT) films were synthesized electrochemically by direct anodic oxidation of 3,4-ethylenedioxythiophene (EDOT) at relatively low monomer concentration (0.005–0.01molL−1) in aqueous solution containing green nonionic sugar-based surfactant N-dodecyl-β-d-maltoside (DM), which has good biocompatibility and biodegradability. The moderate interaction between DM through the hydroxy groups and EDOT monomer led to the decrease of monomer oxidation onset. Different surfactants, such as anionic sodium dodecylbenzenesulfate (SDBS), nonionic triton X-100 (TX100), were also tested for comparison. As-formed PEDOT films were characterized electrochemically and spectroscopically using FTIR and UV–visible techniques. PEDOT nano-materials with good thermal stability and conductivity of 26.2Scm−1can be synthesized in water-DM micellar solution, which can be proved by the results of scanning electron microscopy (SEM). PEDOT prepared from water-DM media with good biocompatibility can be a good candidate for application in biosensors.
