反胶束体系中合成聚苯胺-无机物复合纳米微粒

利用阴离子型表面活性剂2—乙基己基琥珀酸钠(AOT)形成的反胶束作为微反应器合成了聚苯胺—氯化银和聚苯胺—硫酸钡复合纳米粒子；考察了搅拌因素和不同合成步骤对聚苯胺—硫酸钡尺寸及形态的影响；并利用TEM，IR，UV—vis，XRD和四探针电导率仪对产物进行了表征，研究结果表明，反胶束法可以有效地应用于有机—无机复合纳米材料的制备。

Synthesis of Polyaniline/Inorganic Nanocomposites in Reverse Micelle

PANI/AgCl and PANI/BaSO 4 nanocomposites were synthesized in reverse micelle with sodium bis(2-ethylhexyl)sulfosuccinate (AOT) as anionic surfactant. The influences of synthesis conditions including stirring and experimental procedure on the morphology of PANI/BaSO 4 were investigated. The morphology of nanocomposites is observed by transmission electron microscope (TEM), and electrical conductivities were measured by four-probe method. The structures were determined by UV-vis, IR spectra and X-ray diffraction analysis. These results show that reverse micelle is an effective nanoreactor for preparing organic-inorganic nanocomposites.
