Abstract

The paper presents the experimental results of an acoustic impedance study of low-frequency (10⁵ Hz) shear elasticity of a colloidal SiO₂ suspension of differently sized particles in polyethylene siloxane liquid PES-2. The agreement of the experimental results obtained by different variants of the acoustic resonance method confirms that the low-frequency shear elasticity of colloidal nanoparticle suspensions is a bulk property.

胶体纳米悬浮液的低频剪切弹性

摘要

本文介绍了在聚乙烯硅氧烷液体PES-2中不同尺寸的胶体SiO ₂悬浮液的低频（10 ⁵ Hz）剪切弹性的声阻抗研究的实验结果。通过声共振方法的不同变体获得的实验结果的一致性证实，胶体纳米颗粒悬浮液的低频剪切弹性是整体性质。
