Abstract

A novel simultaneous milling and coating method which utilizes a fluid energy mill (FEM) is applied for the first time to prepare nanoparticle-coated CaCO3 additives for polymer composite materials. Simply milled (without coating) CaCO3 particles and as-received CaCO3 particles were used as references for comparison. The effects of the grinding pressure and the content of the coating on the particle size and flowability of CaCO3 were studied. The composites made of PP and this specially prepared CaCO3 have larger elongation at break, elastic modulus and impact strength, compared to the simply milled calcium carbonate filled samples.
