Rheological properties of nanocrystalline cellulose suspensions.
Rheological behavior, including linear and nonlinear, as well as transient rheology of nanocrystalline cellulose (NCC) suspensions was studied in this work. Two kinds of polymer solutions, aqueous poly(vinyl alcohol) (PVA) with flexible chain structure and aqueous carboxymethyl cellulose (CMC) with semi-rigid chain structure, were used as the suspension media to further explore the role that th...
متن کاملRHEOLOGICAL PROPERTIES OF CELLULOSE-NaOH COMPLEX SOLUTIONS: FROM DILUTE TO CONCENTRATED STATES
Steady-state shear flow of cotton cellulose dissolved in a NaOH complex solution (8% NaOH/6.5% thiourea/8% urea aqueous solution) was studied over a large range of concentrations (0-6.2%) and temperatures (0-20 oC), to guide the spinning conditions. The formation of cellulose aggregates was favored when either the cellulose content or temperature was increased. The solution flow curves exhibite...
متن کاملEffect of Polyanionic Cellulose Polymer Nanoparticles on Rheological Properties of Drilling Mud
Polyanionic cellulose polymer is used as an additive in drilling mud in order to decrease water loss and mudcake- thickness. In this study effect of bulk and nanosize polyanionic cellulose on water loss and mud-cakethickness in mud drilling is investigated. Polyanionic cellulose nanoparticles are made by using of ball milling. Size of nanoparticles is measured by Particle size analyzer. Polyani...

The main objective of this work is to characterize the rheological behavior of poloxamer 407 solutions and gels in various shear flow fields.
متن کاملRelating foam and interfacial rheological properties of β-lactoglobulin solutions.
We have determined bulk rheology of β-lactoglobulin (BLG) foams and surface viscoelasticity of corresponding protein solutions by varying pH as well as type, valency and concentration of the added salt in a wide range. Foam rheology was characterized by the storage modulus G0, the apparent yield stress τy, and the critical strain γc,foam defining the cessation of the linear viscoelastic respons...
