【Abstract】 The relationship between the powder’s specific surface area and surface free energy is discussed from a theoretical perspective.The interaction between nano particles in the suspension liquid is analyzed.Measures are proposed to enhance the dispersibility of nano particles,which include increasing the absolute value of the particle’s surface potential,forming a polymer adsorption layer on the particle’s surface,increasing the water affinity of the particle’s surface for the dispersion medium,etc.更多还原
