Remarks: |
Fabrication of biomimetic laminated composite by mimicking the cyclical matrix control processes to form the highly structured Mollusca nacre is presented in this paper. (PDAC/PSS)n self-assembled multilayers were built-up through alternative absorption of polycation and polyanion to a substrate as matrices and their chemical structure were characterized by UV-Vis absorption spectra. And then the deposition of CaCO3 took place on the multilayers by dipping them into a supersaturated CaCO3 solution. The morphology and the structure of the CaCO3 crystals were characterized by SEM and X ray diffraction respectively. With (PDAC/PSS)15 the hexagonal crystals of CaCO3 with the pellet size of 10-20mm, which were very similar to the crystals existed in nacre, was obtained after 10 hr deposition. |
