報告摘要:

? ? ? We have been studying various?polymers and their composites?with?interesting?functionalities?under external fields, in which the external fields imply typical flow fields of laminar flow with most cases of rheological aspects and turbulent flow, electric and magnetic fields. They include non-Newtonian fluid mechanics with flow fields of rod-climbing, turbulent drag reduction, suspension rheology, and polymer nanocomposites in addition to conducting polymer based electrorheological (ER) fluids under an electric field,?while magnetorheological (MR) suspensions have been characterized under applied magnetic fields.

? ? ? Among these, polymer induced turbulent drag reduction along with DNA dynamics, ER and?MR fluids will be covered, and specific?focus will be put on the ER and MR fluids. Various electro-responsive ER materials include?conducting polymers and their derivatives, polymer/clay nanocomposite, polymer/mesoporous composite and carbon nanotube or graphene oxide associated systems?from material rheological viewpoint. Interesting characteristics of their ER suspensions such as?yield stress analysis using universal scaled yield stress concept, flow curve behavior and dielectric analysis?will be reviewed. Its analogy under applied magnetic fields using magneto-responsive MR materials will also be delivered, in which our efforts include?improving MR characteristics of various?magnetic particles. Coating the surface of carbonyl iron?particles producing favourable core-shell structure along with apparently decreased density for synthesized composite particles with several polymers?will be covered in addition to various coatings for both MR fluids and MR elastomers along with their applications.
