报道了一种在Triton X-100存在下，通过苯胺和吡咯混合物的氧化聚合一步法制备聚(苯胺-吡咯)共聚物(PACP)中空纳米球的方法。研究发现，聚合条件的变化，如Triton X-100和共聚单体的浓度，以及[吡咯]/[苯胺]摩尔比的变化，都会改变共聚物中空纳米球的大小和均匀性。DLS结果表明，在反应体系中存在由共聚单体溶胀的球形Triton X-100胶束，这种胶束可能为中空纳米球的形成提供了模板，进而形成了可能的形成机理。通过红外光谱、紫外-可见光谱、核磁共振氢谱和X射线衍射谱对产物的化学结构和结晶度进行了表征，证明了中空纳米球的共聚化学结构。与均聚物(聚苯胺和吡咯)相比，PACP的热稳定性和溶解性得到了改善。#2008威利期刊公司J Polym Sci Part A：Polym Chem 46：3563-3572,2008
A one-step route has been reported for the fabrication of poly(aniline-co-pyrrole) (PACP) copolymer hollow nanospheres via the oxidation polymerization of a mixture of aniline and pyrrole in the presence of Triton X-100. It was found that the variations in polymerization conditions, such as the concentrations of Triton X-100 and comonomers, and [pyrrole]/[aniline] molar ratios, could change the size and uniformity of copolymer hollow nanospheres. The result of DLS has attested the presence of the spherical Triton X-100 micelles swelled by the comonomers in reaction system, and such micelles might play template for the formation of hollow nanospheres, followed by developing a possible formation mechanism. The chemical structures and crystallinity of products were characterized by FTIR, UV–visible, 1H NMR spectra, and XRD patterns, respectively, to prove the copolymer chemical structures of hollow nanospheres. The thermal-stability and solubility of PACP were improved compared with homopolymers (polyaniline and pyrrole). © 2008 Wiley Periodicals, Inc. J Polym Sci Part A: Polym Chem 46: 3563–3572, 2008
