Nanocellulose electrical conductivities

BC/ PPy-APS composite. They explained this behavior by three main reasons (i) the highest electrical conductivity of PPy-FeCl coating layer (ii) BC/PPy FeClj composite showed higher PPy content than those found for BC/PPy-APS system at the same monomer concentration and finally, (iii) morphological differences between BC/PPy FeClj and BC/PPy APS composites, as seen in SEM micrographs. This work thus showed that the oxidative polymerization of pyrrole in a bacterial cellulose (BC) hydrogel can be an effective way to develop novel nanocellulose-based electrically active materials which can be explored for new technological applications. 

Properties and characterization of electrically conductive nanocellulose-based composite films... 

A similar approach was also considered by Valentini et at [171] that successfully prepared homogeneous and conductive cellulose nanocrystals/graphene oxide (GO) composite films. The authors proved how the application of an electric current through the composite leads to the formation of a conductive NCC/GO film highlighting many exciting functional properties of graphene-based nanocellulose composites.
