Abstract:
Renewable resources-derived nanocomposites are receiving extensive attention because of increasing environmental concern and restricted availability of petrochemical resources. The thiol-ene reaction of cysteamine hydrochloride and allyl-etherified trehaloses (AxTs) with allyl functionalities of x = 6 and 8 produced aminated trehaloses (NxTs). Sorbitol polyglycidyl ether (SPE) was cured with NxTs in the presence or absence of cellulose nanofibers (CNFs) to give all carbohydrate-based nanocomposites (SPE-NxT/CNFs) or cured resins (SPE-NxTs). The α-dispersion temperature (Tα) of SPE-N6T was higher than that of SPE-N8T. The Tα for SPE-N6T/CNFs was lowered with increasing CNF content over the range of 0-5 phr, and shifted from lowering to rising at 10 phr. The Tα for SPE-N8T/CNFs was not lowered with increasing CNF content, and SPE-N8T/CNF 10 phr exhibited the highest Tα among SPE-N8T/CNFs 0-10 phr. The tensile strength and modulus of SPE-N6T/CNF 10 phr were the highest among all the samples, which were much higher than those of SPE-N6T.
