通过苯胺和吡咯单体在含有阴离子球形聚电解质刷的酸性介质中化学氧化聚合，成功制备了阴离子球形聚电解质刷/导电聚合物（ASPB/CP）复合材料。通过场发射扫描电子显微镜、透射电子显微镜、傅里叶变换红外光谱、zeta 电位、X 射线光电子能谱和四探针法对这些复合材料进行了表征。结果发现聚苯胺吡咯共聚物均匀地涂覆在ASPB的表面。此外，掺杂ASPB后，ASPB/CP复合材料比纯共聚物具有更高的掺杂水平。此外，这些复合材料还表现出比纯共聚物更好的溶解度和储存稳定性。室温下 ASPB/CP 复合材料的电导率为 7.2 S/cm，而相同条件下纯共聚物的电导率为 2.4 S/cm。
The composites of anionic spherical polyelectrolyte brushes/conducing polymer (ASPB/CP) have been successfully prepared by chemical oxidative polymerization of aniline and pyrrole monomers in an acidic medium containing anionic spherical polyelectrolyte brushes. These composites were characterized by field emission scanning electron microscopy, transmission electron microscopy, Fourier-transform infrared spectrometry, zeta potentials, X-ray photoelectron spectroscopy, and four probe methods. It was found that the poly(aniline-co-pyrrole) was uniformly coated on the surface of ASPB. Besides, the ASPB/CP composites had higher doping level than the pure copolymer after doping with ASPB. Moreover, these composites also showed better solubility and storage stability than pure copolymer. The electrical conductivity of the ASPB/CP composites at room temperature was 7.2 S/cm, while it was 2.4 S/cm for the pure copolymer under the same circumstances.
