A composite aerogel conductive material was prepared by in situ polymerization of cellulose nanofibrils (CNF) as the binder and graphene nanosheets (GNS) as the conductive medium, with aniline. Polyaniline (PANI), which is formed by the acid doping polymerization of aniline, has conductive properties. Nanocellulose has a large specific surface area, high mechanical strength, renewable and degradable properties, and a high aspect ratio, which allows for the effective dispersion of the agglomeration of graphene and polyaniline. This paper studied the effects of different aniline contents on the properties of composites when CNF:GNS ratio is 1:1, and the advantages of 3D porous aerogel conductive materials compared to traditional film-based materials.

通过将纤维素纳米原纤维（CNF）作为粘合剂和石墨烯纳米片（GNS）作为导电介质与苯胺进行原位聚合，制备了复合气凝胶导电材料。通过苯胺的酸掺杂聚合反应形成的聚苯胺（PANI）具有导电性能。纳米纤维素具有大的比表面积，高的机械强度，可再生和可降解的特性以及高的长径比，这允许有效分散石墨烯和聚苯胺的团聚。本文研究了CNF：GNS比为1：1时不同苯胺含量对复合材料性能的影响，以及3D多孔气凝胶导电材料与传统薄膜基材料相比的优势。
