Low-Frequency Shear Elasticity of a Colloid Nanosuspension

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.
