Cellulose Nanofiber/Reduced Graphene Oxide Hybrids as a Novel High- Performance and Biodegradable Reinforcement- Part 1: Preparation Method

Nowadays, high performance and biodegradable reinforcements have a great potential to use in polymer composites. Cellulose nanofiber with natural and renewable resources, is one of the most interesting reinforcement fiber, which widely used in bionanocomposites; But it is essential to improve the mechanical and thermal properties of these fibers. In this research, the new type of biodegradable reinforcement based of cellulose nanofiber (CNF) and reduced graphene oxide (RGO) is prepared via layer by layer assembly (LbL) method. Hybridizing of RGO nanosheets and cellulose nanofibrils is a promising feat. XRD, FTIR and UV-Vis analysis, show that CNFs have good interfacial contact with RGO. It is expected that, the bonding between neighboring RGO nanosheets is enhanced by CNF, because the introduction of CNF provides the extra bonding options available between the nanosheets, which led to noticeable enhancement in mechanical properties
