Cellulose nanocrystals (CNCs) can be used in various applications owing to their biocompatibility, solution-processability, and mechanical flexibility. One of the promising applications of CNCs is electric gas sensors. For this, conducting materials should be incorporated with CNCs to increase conductivity. Meanwhile, graphene, which is a novel material having high conductivity, can be dispersed in water and well-mixed with CNCs. In this respect, CNCs and graphene dispersed in water (GDW) can be an excellent combination for a biocompatible gas sensing material. For developing efficient gas sensors using CNC:GDW, a fundamental understanding of CNC:GDW film properties including electronic structure and morphology is of great importance. In this study, we fabricated and characterized CNC:GDW composite films. The conductivity of the flexible CNC:GDW films were increased with an increase in the GDW concentration. The morphological property and electronic structure of CNC:GDW films were investigated using scanning electron microscopy and X-ray photoelectron spectroscopy. Based on these results, we demonstrate the high potential of CNC:GDW films for gas sensor applications.
