Abstract

The complex shear modulus of silicon dioxide nanoparticle suspensions in a polyethylsiloxane liquid is determined via acoustic resonance using a piezoelectric crystal. The technique is based on studying effect additional coupling forces have on the resonance characteristics of an oscillating system. Specific features of the dependence of the shear modulus on the deformation amplitude are due to intermolecular interactions in suspensions, determined via IR spectrometry.

用声学方法研究纳米悬浮液的剪切弹性非线性

摘要

聚乙基硅氧烷液体中二氧化硅纳米粒子悬浮液的复数剪切模量是使用压电晶体通过声共振确定的。该技术基于研究附加耦合力对振荡系统共振特性的影响。剪切模量对变形幅度的依赖性的特定特征是由于悬浮液中的分子间相互作用，通过红外光谱测定。
