The dispersing of nanosized particles is a new developing technique, which usually shows special effects. Compared with normal block materials, nanosized particles have several advantages in physical and chemical properties, surface, and interface characteristics. However, nanosized particles have huge specific surface area and surface energy, which easily result to aggregation of nanosized particles and inhibit the effect of nanosized particles. In this thesis, a water-soluble hyperdispersant, which...
