摘要: A microrheological model of aggregating dispersions is proposed in which the shear stress estimated as sum hydrodynamic and structural parts. The former attributed to cores fractal aggregates, behave a suspension impermeable spheres. latter accounts for forces transmitted by chains particles linking neighboring aggregates into transient network. To calculate part concept aggregation incorporated network theory, account creation breakup colloidal connecting aggregates. Rigid soft are distinguished. have multiply connected backbones deform contorted elastic rods, while at least one junction without resistance until fully loaded. contribution tensor neglected. calculations treat two different mechanisms evolution rigid chains: purely m...
