Abstract

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.
