PREPARATION OF α-CHITIN NANOFIBER BASED COMPOSITE

摘要：

　　The chitosan(CS)solution were filled with the partially deacetylated α-chitin nanofibers(DEChN)and the composite(DEChN/CS)beads prepared.The filling of chitin nanofibers resulted in the increasement of the shearing modulus(G,G),that indicated an improvement of the mechanical property of the DEChN/CS composite beads.Meanwhile,the specific surface area was improved from 46.47m2/g to229.71m2/g when the chitosan beads were filled withthe chitin nanofibers,and the prepared DEChN/CS composite beads had a broad pore size ranging from 20 nm to 60 nm.Moreover,a more porous and fibrous structure in the SEM image of DEChN/CS beads was observed than that of the sole CS ones.The chitin nanofibers provided a fibrous network in the chitosan matrix that enhanced both the mechanical and porous property of DEChN/CS composite beads,which was normally considered as the contradictory material characteristics.
