Thixotropic Properties of Polyacrylamide Hydrogels with Various Synthetic Conditions
Abstract:Influences of synthetic conditions and water content on rheological properties of polyacrylamide hydro gels were studied. The non-Newtonian flow curves of polyacrylamide hydrogels were obtained by using a cone-plate rhe ometer. The rheological parameters were obtained by applying non-Newtonian equation to the flow curves for polyacrylamide hydrogels. The polyacrylamide hydrogels are shear thinning under increasing shear rate modes which result in thixotropic behavior. These flow properties are controlled by th… Show more
