[2P43] Electrical property of carbon nanotube/cellulose nanofiber composite sheets
Carbon nanotubes (CNTs), which have many excellent properties such as high strength, high electrical conductivity and so on, are expected to be a constituent of composite materials. Composite materials with CNTs have excellent mechanical properties than conventional materials because of reinforcement by the CNTs. In addition, it is possible to give electrical and thermal conductivity by adding CNTs in the matrix. Among those, composites of cellulose nanofibers (CNFs) and CNTs have recently been studied from the viewpoint of function of material. CNFs are made by fibrillation of cellulose and have lightweight and high mechanical strength characteristics. By combination of CNTs and CNFs, it is expected to create further excellent composite material with high mechanical strength, high electric and thermal conductance, and light weight. In this study, we formed CNT/CNF composite sheets and examined those electrical characteristics for purpose of application to flexible electronics.
