| 摘 要： | 通过用紫外-可见-近红外光谱、X射线光电子能谱及透射电镜等手段对采用反向胶束合成法,以二乙基磺基琥珀酸钠(AOT)形成的反胶束为模板制备出的导电聚合物聚3,4乙烯二氧噻吩(PEDOT)纳米粒子对HCl气体敏感性进行研究。沉积有纳米粒子的QCM器件对2.0×10-5气体响应时间为20s,具有较好的响应恢复特性,能够有效探测低浓度(5×10-6)气体,气敏特性明显优于普通PEDOT粒子。

| Abstract: | Based on a new type of conducting polymer poly(3,4-ethylenedioxythiophene)(PEDOT),this paper focused on the preparation and gas sensitivity of PEDOT nanostructure with reversed micelle method.PEDOT nanoparticles were characterized to gas sensitivity by different methods,such as ultraviolet/visible(UV-Vis) spectroscopy,X-ray photoelectron spectroscopy(XPS) and so on.The latest investigation of gas sensitivity of PEDOT nanoparticles to HCl gas was carried out,and it has been found that the response time of PE... |
