| Research Abstract |
Carbon nanotubes(CNTs) are fibrous crystalline material which have several to several ten nanometers in diameter. CNTs shows high mechanical strength close to the theoretical value, then the application as the structural material. In this study, preparation of the monolith and composite of CNTs and their application for dental and medical materials were studied. CNTs were successfully sintered using the spark plasma sintering and CNTs monolith showed similar elastic modulus to bone. CNTs/collagen composite films were also prepared. The film shows good tensile strength and flexibility.
