Abstract

Data on the bulk viscosity of an aqueous suspension of SiO₂ nanoparticles (Ludox TM-50) have been obtained for the first time using an acoustic spectrometer. A wide range of nanoparticle mass concentrations (from 1 to 50 wt %) has been investigated. Spectra of the ultrasound attenuation coefficient and coefficients of longitudinal and dynamic viscosities have been measured. Dependences of the dynamic and bulk viscosity coefficients of the suspensions on the nanoparticle concentration have been obtained.

二氧化硅纳米颗粒悬浮液的体粘度

摘要

首次使用声谱仪获得了有关SiO ₂纳米颗粒水悬浮液（Ludox TM-50）的体积粘度的数据。已经研究了宽范围的纳米颗粒质量浓度（1至50重量％）。已经测量了超声衰减系数的光谱以及纵向和动态粘度系数。已经获得了悬浮液的动态和体积粘度系数与纳米颗粒浓度的依赖关系。
