摘要 在常温条件下,以过二硫酸铵(APS)为氧化剂,同时利用杂多酸H4SiW12O40作为质子酸和制备导电聚合物的掺杂剂,通过液固相化学氧化聚合方法成功地合成出杂多酸掺杂的纳米纤维形貌的导电聚苯胺(PANI)材料.以红外光谱、紫外-可见光谱、X射线粉末衍射光谱和扫描电镜等测试手段对杂多酸掺杂PANI纳米纤维结构材料进行了表征.并测定了其导电性,发现该材料的电导率为5.5S/cm. PANI nanofibers is successfully obtained by liquid solid phase chemical oxidative polymerization method at the condition of normal temperature, ammonium peroxydisulfate(APS) is used as oxidant, and H4SiW12 O40 is used as dopant. The PANI nanofibers is characterizated by IR spectra,UV-vis,XRD pattern and SEM. The electronic conductivity of the PANI is also measured by four-probe method. The electronic conductivity of PANI nanofibers is 5.5 S/cm.
