Facile synthesis of monodispersed barium sulphate particles via an in situ templated process.
Monodispersed BaSO4 micrometer and submicrometer sized particles were produced by a simple precipitation reaction in the presence of poly(methacrylic acid) (PMAA) at the ambient temperature. Scanning electron microscopy (SEM), transmission electron microscopy (TEM), X-ray diffraction (XRD) and electron diffraction (ED) were used to characterize the obtained BaSO4 particles, and polycrystalline nature of the BaSO4 products was revealed. A "polymer-M in situ template" model was proposed to elucidate the formation process of such polycrystalline BaSO4 particles.
