basic information
**Course Objectives and Aims** After an explanation of the dispersion mechanisms of fine particles that can be commonly handled in both aqueous and organic solvent systems, we will discuss the stabilization and evaluation techniques for fine particle dispersion that are characteristic of organic solvent systems. We will summarize the methodologies for grafting polymers onto the surfaces of nanoparticles such as silica and carbon nanotubes. Next, we will describe the diverse functionalization of nanoparticle surfaces through the grafting of antibacterial polymers, biorepellent substances, flame retardants, and even light stabilizers. Furthermore, we will also introduce the control of dispersion properties of nanoparticles through surface grafting.
