Fabrication, Structure, and Properties of Chitin Whisker-Reinforced Alginate Nanocomposite Fibers

摘要: Calcium alginate yarn (30 fibers) and cal- cium nanocomposite containing 0.05-2.00% w/w chitin whiskers were both prepared by wet spinning process. The acid hydrolysis of from shrimp shells. average length width the 343 46 nm, with aspect ratio being � 7.5. Incorporation a low amount in fibers improved mechanical thermal properties significantly, possibly result specific interactions, i.e., hydrogen bonding electrostatic between molecules homogeneously dispersed whiskers. Biodegrada- tion calcium was tested Tris-HCl buffer solution same that contained lysozyme. addi- nanocomposites accelerated biodegradation process presence lysozyme, whereas Ca 2þ ions helped to improve te- nacity fibers.
