Abstract Multifunctional conducting polyaniline/hexaferrite aerogels supported by poly(vinyl alcohol) have been prepared by simple one-step procedure. The incorporation of magnetic particles into aerogel matrix was successfully proven with scanning electron microscopy and by examination of magnetic properties. Such novel hybrid aerogels showed better resistance against elastic deformation when stress is applied, increased conductivity compared to neat polyaniline/poly(vinyl alcohol) cryogels, and also enhanced coercive force compared with neat hexaferrite due to increased effective magnetic anisotropy by magnetostriction. Moreover, the efficient adsorption of Reactive Black 5 dye by aerogel has been illustrated. Therefore, this work offers new type of macroporous dye adsorbents which can be efficiently separated from the aqueous medium and thus used for wastewater treatment.

具有磁性去除有机染料的导电聚合物复合气凝胶

摘要 通过简单的一步法制备了以聚乙烯醇为载体的多功能导电聚苯胺/六铁氧体气凝胶。通过扫描电子显微镜和磁性检测，成功地证明了磁性颗粒掺入气凝胶基质中。这种新型混合气凝胶在施加应力时表现出更好的抗弹性变形能力，与纯聚苯胺/聚乙烯醇冷冻凝胶相比具有更高的导电性，并且由于磁致伸缩增加了有效磁各向异性，与纯六铁氧体相比，矫顽力也增强了。此外，还说明了气凝胶对活性黑 5 染料的有效吸附。所以，
