Abstract:
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 nonNewtonian flow index of the blend solutions decreases with the increasing of temperature and HAP mass fraction.Overall, PES-HAP blend solution is nonNewtonian fluid.
