摘要
Nanocomposites composed of a water-soluble nylon (P-70, polyalkyleneoxide-modified poly(-caprolactum), and chitin nanofibers (ChNFs) were prepared by a casting method of the aqueous resin/fiber dispersion. P-70 was crosslinked with a resol-type phenolic resin (PR) and its ChNF nanocomposites were prepared to provide water resistance. The P-70/PR and P-70/PR/ChNF exhibited excellent water-resistance. The FT-IR analysis revealed that the crosslinked structure was formed by the reaction of amide groups of P-70 and methylol groups of PR. The glass transition temperature (T-g) of P-70/PR increased with increasing PR content, whereas the dispersion of ChNFs was deteriorated. Although the addition of ChNF to P-70 hardly affected the T-g, the addition of ChNF to P-70/PR caused a lowering of T-g. The tensile strength and modulus for P-70/ChNF nanocomposites increased with increasing ChNF content. The tensile strength of P-70/PR was lower than that of P-70, which increased by the addition of ChNF.
