Preparation and Properties of Optically Transparent Chitin Nanofibers Sheet by Different Simple Mechanical Methods

摘要: Chitin nanofibers were prepared from commercially available dried chitin powders by different simple mechanical methods under acid conditions after removal of minerals and proteins. The fibrillated samples observed FE-SEM there was a fine network structure formed nanofibes with width approximately 10-50 nm high aspect ratio. treatment crucial to facilitate the fibrillation fibers into nanofibers. pressure homogenization in combination grinding used obtain most transparent sheet transmittance 88.5% tensile strength 82.34MPa, even had Young’s modulus 6.17GPa. Thus, provide excellent potential as reinforcement flexible composites improve properties nanocomposites.
