Development of nanofiber reinforced resin using various nanotubes

碳纳米管（CNTs）是一种直径为几到几十纳米的纤维状晶体材料。碳纳米管显示出接近理论值的高机械强度，然后作为结构材料的应用。本论文主要研究了碳纳米管整体材料和复合材料的制备及其在牙科和医用材料中的应用。碳纳米管成功地烧结使用放电等离子烧结和碳纳米管整料显示出类似的弹性模量骨。还制备了碳纳米管/胶原复合膜。该膜显示出良好的拉伸强度和柔韧性。

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.
