利用表面活性剂乳液自组装产生模板,以磺基水杨酸为掺杂剂,苯胺(ANI)为油相,稀土(Ce-Pr)离子水溶液为水相,形成反胶束微乳液,使稀土粒子均匀分散于油相中,成为热力学稳定的乳液体系,将该乳液插层于有机蒙脱土(MMT)的片层间,加入引发剂单体直接进行原位聚合,即制得目标产物.通过红外光谱(IR)、扫描电镜(SEM)、X-射线衍射(XRD)和差热-热重(TG-DTA)对该复合材料进行了表征和分析.结果表明,反胶束法制备出热稳定性良好的新型PANI/Ce(OH)3-Pr2O3/MMT纳米复合材料,该法可以用于三相纳米复合材料的制备.
The use of surfactant emulsion self-assembly template, sulfosalicylic acid as a dopant, aniline (ANI) as the oil phase, rare earth (Ce-Pr) ion aqueous solution as the water phase to form a reverse micelle microemulsion, the rare earth The particles are uniformly dispersed in the oil phase and become a thermodynamically stable emulsion system. The emulsion is intercalated between the layers of the MMT, and the initiator monomer is directly polymerized in situ to obtain the target product. The composites were characterized and analyzed by IR, SEM, XRD and TG-DTA.The results showed that the composites were prepared by reverse micelles The new PANI / Ce (OH) 3-Pr2O3 / MMT nanocomposites with good thermal stability can be used in the preparation of three-phase nanocomposites.
