Nacre-inspired green artificial bionanocomposite films from the layerby-layer assembly of montmorillonite and chitosan

The simple LBL technique was introduced to fabricate green nacre-like chatosan/montmorillonite (CHI/MMT) films. The results of SEM and XRD analysis demonstrate that the produced CHI/MMT composites films stacked densely together to bring out well-defined nacre-like brick-mortar structure. The nanoind...

Description
Summary:The simple LBL technique was introduced to fabricate green nacre-like chatosan/montmorillonite (CHI/MMT) films. The results of SEM and XRD analysis demonstrate that the produced CHI/MMT composites films stacked densely together to bring out well-defined nacre-like brick-mortar structure. The nanoindentation technique is used to characterize the mechanical properties of the layered nanocomposite films, which show enhanced mechanical modulus (up to ∼6.64 GPa) compared with the pure chitosan.
