Abstract: Composite mineral particles with nano-structured surface, which effectively improve surface morphology of the originals and increase specific surface area, were successfully prepared by using a chemical method. By wet grinding in a stirring mill, the coalescence between coating particles and the base was discussed. The preliminary conclusion gained shows that the coating particles are not easy to be peeled off from the base because of chemical absorption. The mechanical properties of the composite are greatly improved, when the coated mineral particles filled in polypropylene.

Key words: inorganic mineral, filler, coating, surface nano-structured particle
