Improving Biomass-Degradation Properties and Nano-Mechanics of Moso Bamboo via a Simple Nitrogen Heat Treatment

Nitrogen is generally used as a protective gas to provide an oxygen-free environment for the heat treatment of biomaterials. In order indicate effect nitrogen bamboo, changes in terms chemical composition, functional groups, cellulose crystallinity index, surface color, micro-mechanics and anti-mildew properties interaction relationship among properties, were analyzed. The mass loss ratio treated bamboo samples increased significantly during process thermal modification. detail, hemicellulose exhibited decreasing tendency from 23.7% 16.6%, while lignin content presented increasing tendency. decreased contents are benefit enhancing degree, thus modulus elasticity hardness cell walls. obtained sample at 190 °C/3 h displayed best micro-mechanical properties. It maximum 22.1 GPa 0.97 GPa. Meanwhile, was proven increase composition analysis, resulting lower free-hydroxyl groups on surface. Thus, contact angle value increased. Furthermore, modification positively contributed mildew resistance specimens.
