| Abstract: | Through a variety of surface additives and nano-particles surface chemical reactions and physical role Surface modification changed the surface state of particles and improved or changed the dispersion of powder and improved the durability, weather resistance, increased surface activity, so that nano-particles surface generated new physical, chemical, optical properties, which made it adapt to different application requirements, thus significantly increased the added value of the material. The paper described the progress on modification of the surface coating and partial chemical modification, mechanical and chemical modification, capsule-based modification, high-energy surface modification and surface modification method of precipitation reaction. |
