Research progress on the correlation between properties of nanoparticles and their dispersion states in polymer matrix

When fabricating polymer nanocomposites (PNCs), it is difficult for nanoparticles to disperse stably in matrix since their high-surface energy can cause them attract each other. In this paper, we review the effects of nanoparticle size, surface chemical properties, and thermodynamic parameters on dispersion state (including inorganic organic particles) PNCs describe some key measures promote dispersion. The ideal melt available when particle size smaller than rotation radius chains highly compatible or has interactions with matrix. solution, establishing proper necessary ensure balance among particles, solvents, polymers, leading successful preparation structure. These results could supply theoretical suggestions design PNCs. Moreover, equilibrium may be unavailable without reasonable kinetic parameters, even if process thermodynamically favorable. Therefore, more studies are required both thermodynamics kinetics process.
