1纳米纤维素纤维的制造方法纳米纤维素纤维是木材等植物细胞壁的基本骨格,宽4~5μm。其弹性模量和拉伸强度分别为150 GPa和2~3 GPa,可匹敌芳香族聚酰胺纤维。其线膨胀系数小,为1×10-7K-1,与石英玻璃相同。从植物细胞壁分离出纳米纤维素纤维的技术目前已有东京大学的TEMPO氧化催化的化学处理法和京都大学的机械法。化学法是木材浆粕微米纤维经TEMPO氧化催
1 nanocellulose fiber manufacturing methods Nano-cellulose fibers are wood and other plant cell walls of the basic bone, width 4 ~ 5μm. The modulus of elasticity and tensile strength of 150 GPa and 2 ~ 3 GPa, respectively, to rival aromatic polyamide fiber. The linear expansion coefficient is small, 1 × 10-7K-1, the same with quartz glass. Techniques for separating nanofibrous cellulose from plant cell walls There are currently TEMPO-catalyzed chemical treatment methods at Tokyo University and Kyoto University’s mechanical method. The chemical method is wood pulp micron fiber TEMPO oxidation reminder
