誘電率の調整によるナノ粒子の分散安定性の制御及び界面活性剤フリーナノ粒子の固有誘電率の決定

Japanese Patent JP7187316

B2

A composition including a medium and surfactant-free nanoparticles (SFNPs) at different dispersion state or aggregation form. The composition includes: (a) a composition of a medium and surfactant-free nanoparticles in primary form, wherein the dielectric constant value (DE value) of the medium is equal to or larger than the intrinsic dielectric constant value (IDE) of the SFNPs and smaller than about 1.5 times of the IDE of the SFNPs; (b) a composition of a medium and reaction-limited aggregation form of SFNPs, wherein the DE value of the medium is much larger than the IDE of the surfactant-free nanoparticles; (c) a composition of a medium and diffusion-limited aggregation form of SFNPs, wherein the DE value of the medium is smaller than the IDE of the surfactant-free nanoparticles; and (d) a composition comprising redispersible aggregation form of surfactant-free nanoparticles, wherein the surfactant-free nanoparticles are induced to aggregate in the diffusion-limited fashion in a medium with a DE value that is smaller than the IDE of the surfactant-free nanoparticles.
