Abstract

The invention discloses a polymer nano gel particle / calcium carbonate composite material and a preparation method thereof, belonging to the technical field of functional nano composite materials. The polymer nanogel particle / calcium carbonate composite material of the present invention uses calcium carbonate crystals as a carrier, and the polymer nanogels are uniformly embedded in the calcium carbonate crystals. The particle diameter of the polymer nanogel particles is 20-500 nm, and the particle diameter of the calcium carbonate is 10-50 μm. The near-monodisperse and stable polymer nanogel particles prepared by the free radical dispersion polymerization method in the present invention are efficiently embedded in the calcium carbonate crystal growth process, which overcomes the crystallization rejection and the incompatibility of different material interfaces sex.
