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

Abstract Nano‐calcium carbonate (nano‐CaCO 3 ) 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‐CaCO 3 . In particular, the preparation process conditions, the characteristics of the prepared nano‐CaCO 3 , the method and mechanism of surface modification, and also the main application research progress of nano‐CaCO 3 are described comprehensively. This paper has a good guiding effect for the researchers and related staff engaged in the study of nano‐CaCO 3 .
