Synthesis and Character of Amphiphobic Calcium Carbonate Nanoparticles In Situ

Abstract:

Article Preview

Amphiphobic vaterite with a size of about 50 nm, was prepared via crystallization of CaCO3 with perfluorooctane surfapropyl betaine(DF-921)in methanol by mimicking the process of biomineralization. The products were analyzed by scanning electron microscopy (SEM), Fourier transform infrared spectroscopy (FT-IR), X-ray diffraction (XRD) and contact angle analysis. The results indicate that the CaCO3 powder samples had both hydrophobic and oleophobic properties. The DF-921 used in this research not only controlled the crystal type of the CaCO3 particles but also changed the surface properties of the final products.
