Research on surface modification of ultrafine-grains

It summarizes the importance of surface modification , reasons of ultrafine-grains conglomerating and functions of surface modification. The different surface modification methods and the simple interaction mechanisms between particle and many kinds of modifier are discussed in detail. By reducing the surface energy of particle and changing the surface polarity of particle, the main purpose of modification is to decrease aggregation of particles and promote dispersion of ultrafine-grains.
