概要 | Glycerol polyglycidyl ether (GPE) and sorbitol polyglycidyl ether (SPE) were cured with tannic acid (TA). The most balanced properties were obtained for the GPE/TA and SPE/TA cured at 160 degree C. The cured SPE/TA had a higher Tg and tensile strength than the cured GPE/TA. Next, biocomposites of GPE/TA and SPE/TA with microfibrillated cellulose (MFC) were prepared by mixing aqueous solution of the epoxy/curing reagent with MFC, and subsequent drying and curing at the optimized condition. For both the GPE/TA/MFC and SPE/TA/MFC biocomposites, Tg and the storage modulus at rubbery plateau region increased with increasing MFC content. The tensile strength for GPE/TA/MFC biocomposite with MFC content 10 wt% was 76% higher than that of GPE/TA. The tensile strength and modulus of SPE/TA/MFC biocomposite with MFC content 10 wt% were 30 and 55% higher than those of control SPE/TA, respectively. |
