Rheological Property of PESHAP Blend Solution

Polyether sulfone (PES) solutions containing hydroxyapatite (HAP) were prepared with dimethyl acetamide (DMAc) as solvent. The rheological curves of the blend solution PES-HAP-DMAc, and the effects of HAP mass fraction and the temperature of the blend solution on the rheological properties were studied. Results show that nonNewtonian flow index of the blend solutions decreases with the increasing of temperature and HAP mass fraction.Overall, PES-HAP blend solution is nonNewtonian fluid.
