Tunable self-assembly structure of graphene oxide/cellulose nanocrystal hybrid films fabricated by vacuum filtration technique

By adjusting the dispersibility of graphene oxide (GO) in cellulose nanocrystal (CNC) aqueous solution, two distinct GO/CNC hybrid films with various internal structure have been obtained via vacuum-assisted self-assembly. After reduction, thus prepared GO/CNC hybrid films respectively demonstrate high conductivity or iridescent properties.
