Abstract

Physicochemical characteristics of silver nanoparticles with known sizes are studied, depending on the concentration of nonionic surfactants and the concentration of the metal. Surfactants are used that form micelles of different sizes and different intensities of light scattering. It is shown that the surface tension and adhesion properties of solutions of nonionic surfactants are determined by the solvent in ranges of concentration lower than 1 mol/L. An approach based on spectrophotometry and viscosimetry is proposed that allows determination of the most likely reasons for discrepancies in the hydrodynamic diameter of nanoparticles in solutions of nonionic surfactants and the actual diameter of the nanoparticles.

非离子表面活性剂溶液中银纳米颗粒的流体动力学直径

摘要

根据非离子表面活性剂的浓度和金属的浓度，研究了已知尺寸的银纳米粒子的理化特性。使用形成不同大小和不同光散射强度的胶束的表面活性剂。结果表明，非离子表面活性剂溶液的表面张力和粘附性能取决于溶剂在浓度低于1 mol / L的范围内。提出了一种基于分光光度法和粘度测定法的方法，该方法可以确定非离子表面活性剂溶液中纳米颗粒的流体动力学直径与纳米颗粒的实际直径差异的最可能原因。
