Interfacial molecular recognition between polysaccharides and calcium carbonate during crystallization.
Based on the basic principles of biomineralization, using beta-cyclodextrin, hepatin and soluble starch as organic matrices, employing the biomimetic method, the crystallization of CaCO(3) was studied by Fourier transform infrared spectroscopy (FT-IR), X-ray powder diffraction analysis (XRD), scanning electronic microscopy (SEM), thermal gravity-differential thermal analysis and conductivity analysis. The results show that polysaccharides have an effect on the crystallization of CaCO(3). CaCO(3) crystals also have an effect on polysaccharides. The possible mechanism of this interaction is discussed.
