Nacres, known as the Mother of Pearl, have been spotlighted in recent years due to their exceptional mechanical properties, originating from the sandwiched structure consisting of 300 ~ 900 nm thick CaCO3 platelets in between 10 ~ 30 nm thick organic mortar layers. In this presentation, CaCO3/polymer hybrid nanolaminates were prepared by the sequential deposition of polymer and CaCO3 layers on the ‘seed’ CaCO3 crystalline layer. Thin polymeric multilayers, composed of (poly(allyl amine)(PAM)/poly(acrylic acid)(PAA))n, were deposited using the layer-by-layer (LbL) deposition. CaCO3 layer was then grown on the surface of ‘polymer-coated seed crystalline layers’. The CaCO3 growth behavior was systematically investigated by varying the thickness of organic layers, using X-ray diffraction (XRD) and field-emission scanning electron microscopy (FE-SEM) |
