The surface structure,surface morphology and active groups of pigments and fillers directly affect the interaction with polymers,the adsorption of polymer has a fundamental effect on the surface properties of cured coatings.In this paper,the influence of inorganic or organic pigments and fillers on the physical chemistry properties of coating materials is discussed from the point of view of their chemical activity,surface defects and morphology,and the basic properties of pigments and fillers in the process of application are described,which may be helpful to the study of the application of pigments and fillers in coating chemistry.
