The surface of calcined kaolinite particles underwent chemical modification using Vinyltriethoxysilane (VTMS) and 3-mercaptopropionic acid (3-MPA). The grafting ratio of VTMS on the calcined kaolinite surface was adjusted by varying its quantity. FT-IR analysis revealed the initial grafting of VTMS onto the kaolinite surface, resulting in the formation of a C=C reactive site on the surface.

- The study focuses on modifying calcined kaolinite with chemical agents to enhance its surface properties for better distribution in various polar dispersion media.
- Two modifiers, 3-aminopropyltriethoxysilane and phenyl glycidyl ether, were used, with analysis showing effective surface modification and improved dispersion performance in different solvents.
- The modified kaolinite particles were incorporated into a PBAT matrix, achieving better mechanical properties, particularly at a 6-8 wt.% loading, by adapting to different polarities thanks to their hydrophilic and hydrophobic characteristics.
