Cellulose nanocrystals (CNCs) extractable from plants have excellent biodegradability and biocompatibility. Also, the CNC films can be easily fabricated via solution process. In this respect, the CNCs are emerging materials for various applications. For a use of CNCs in electronic devices, mixing CNCs with other functional nanomaterials can be an efficient strategy to increase conductivity. In this study, we fabricated and characterized CNC-graphene hybrid films on a polyethylene terephthalate substrate using a bar-coating method. The changes in the sheet resistance of the flexible CNC films were observed by varying the graphene dispersion ratio. The structural property and electronic structure of CNC-graphene films were investigated using scanning electron microscopy and X-ray photoelectron spectroscopy. Based on these results, we discuss the physical origin of changes in the sheet resistance. In addition, we fabricated the CNC-graphene paper by adding a glycerol additive. The properties of the CNC-graphene paper were significantly varied by the choice of a graphene dispersion type. The use of graphene dispersion including functional groups results in higher uniformity. Thus, the same sheet resistance values of CNC-graphene paper could be obtained on both front and back sides.
