文摘The spherical CaCO3 composite was synthesized in the presence of the amphiphilic block copolymer, i.e. polystyrene-b-poly(acrylic acid). It was revealed by XRD analysis that the grains in the composite was calcite with great distortion. Infared and Raman analysis showed that the composite was composed of PS-b-PAA calcium salt and calcite, and the calcite was nano-scaled.
