Ethylene acrylic acid copolymer(EAA)/cellulose nanofiber(CNF) nanocomposites were successfully prepared by green and simple water-assisted mixing followed by film casting. EAA was dispersed in water neutralized by ammonia, and the stable aqueous dispersion of EAA mixed with CNF water suspension. The morphology, thermal and mechanical properties of the nanocomposites were studied using TEM, DSC, DMA, and tensile testing. The experimental results showed that CNF were homogenously dispersed into the EAA matrix and provided significant reinforcement of the EAA. The presence of a rubbery plateau above the melting temperature of EAA/CNF nanocomposites obtained from DMA indicated that the nanocomposites formed a physically cross-linked structure. The EAA/CNF nanocomposites also exhibited an excellent thermally triggered shape memory effect. |
