one of the indirect methods for the measurement of melt viscosity by rheometer in which viscosity can be measured by shear rate. this is an analytical technique for nancomposites.
Actually, I want to see the effect of clay loading on Polyvinyl alcohol/Bentonite solution so this is an indirect technique to analyze the clay loading effect on the rheology of PVA solution.
please recommend me some article related to the experimental procedure for the rheology of PVA.
