These materials have excellent functions if nanoparticles disperse well in matrix. Nanoparticles can aggregate easily with decreasing particle size because the number of active sites on particle surface increase. Interaction energy working among particles is greatly influenced by physicochemical properties of medium and dispersing components. In order to show these functions sufficiently, nanoparticle dispersion behavior in slurry should be clarified. In this study, we have proposed a new technique to characterize particle dispersability in slurry which can be applied to any kinds of dispersing systems. This technique provided new information on particle dispersion which has been never obtained using conventional methods such as rheological and electrokinetic analysis. Additionally, surface treatment technique on molecular level has been developed. We have improved nanoparticle dispersability in matrix and characterized modified surfaces., application/pdf}, pages = {32--39}, title = {ナノサイズ無機粒子の水系/非水系における分散性制御とその評価に関する研究}, volume = {6}, year = {2007}, yomi = {タカイ, チカ and フジ, マサヨシ and タカハシ, ミノル} }
