Rheological Dynamics of Liquid Crystal-coupled Nanocomposites under Influence of Thermal Gradients: Albree Weisen1; Harini Sridharan1; Joshua Seylar1; Ruel McKenzie1; 1The University of Akron - Department of Polymer Engineering
Presented in this study is the synthesis and characterization of heat flux effects on the rheological properties of liquid crystal-coupled silica nanocomposites (Si-LCNCs) dispersed in an isotropic medium. To understand the impact of thermal flux on the rheological properties of the nanocomposite, a customized thermal flux system is integrated into a torsional shear rheometer. Of particular interest is the concentration dependent behavior under these conditions. At low concentrations, solvent-particle interactions are typically dominant, causing thermophoresis to occur and thereby impacting rheological behavior. Conversely, at higher concentrations particle-particle interactions will begin to dominate, limiting thermophoresis which may lead to emergent behavior from the induced thermal stress. However, what is not apparent is the mode by which heat transfer properties are impacted by shear. This study will present some of the phenomenological findings on the interrelationships between heat transfer and suspension flow.
