Review on Preparation, Modification and Application of Nano‐Calcium Carbonate

Abstract

Nano‐calcium carbonate (nano‐CaCO3) is a tiny inorganic filler created in the 1980s. It boasts a high specific surface area, excellent biocompatibility, and nontoxicity. As a result, it finds extensive applications in the rubber, plastic, and paper industries. This paper intends to give a general overview of the preparation process, surface modification, and application of nano‐CaCO3. In particular, the preparation process conditions, the characteristics of the prepared nano‐CaCO3, the method and mechanism of surface modification, and also the main application research progress of nano‐CaCO3 are described comprehensively. This paper has a good guiding effect for the researchers and related staff engaged in the study of nano‐CaCO3.
