Powder surface modification changes the surface state of particles through physical or chemical means, with the core being to break the agglomeration force between particles. When the particle size of the powder decreases to the micrometer or nanometer level, the surface energy sharply increases, and van der Waals forces, hydrogen bonds, and other gravitational forces cause the particles to sponta...

Why modify the powder? Inorganic powders have hydrophilic and polar surfaces, but poor compatibility with organic matrices (plastics, rubber, resins). Direct use can lead to poor performance, so modification is necessary. (1) Improve dispersibility and prevent agglomeration. Inorganic powders with a large specific surface area are prone to agglomeration, which can lead to defects and a decrease in...
