In nature, nacre has the hierarchical brick-and-mortar structures and precise inorganic-organic interfaces, which enable it to achieve remarkably high fracture toughness and tensile strength. Because of these properties, nacre-mimetics hold great potential as mechanical high-performance and functional materials. Previously, we have fabricated nacre-like nanocomposites via vacuum filtration of montmorillonite(MMT) and cellulose nanofibers(CNFs) mixtures. Although the composites exhibited higher strength and toughness than pure MMT and CNFs, we tried to improve the mechanical properties further y by additional post treatmentsive work. In this study, adding polymers and cross-linking were introduced to improve the mechanical propertiesy of the composites. The resulting materials were analyzed by a Scanning electron microscopy(SEM), an X-ray diffraction(XRD), and a tensile tester. We compare the resulting mechanical properties with the previous results. |
