Electrorheological (ER) polishing as a new type of technique has flexibility and controllability. However, ER cannot be widely used in actual processing because the present fluid is usually prepared by simple mixing abrasive materials into fluid, which easy to occur phase separation decreased performance. This paper develops material based on cerium-doped titanium dioxide. As classic abrasive, ...

A microfluidic device with a microvalve incorporated intelligent giant electrorheological fluid (GERF) was proposed to actively and accurately control micro-droplet merging in various droplet scales. The GERF is suspension without an additional electric field, its viscosity can be increased the increase voltage. chamber composed of expanded channel thin membranes on both sides several pillars u...

Electrorheological fluids are smart materials that are concentrated suspensions of polarizable particles in a nonconducting dielectric liquid. In moderately large electric fields the particles form chains along the field lines and these chains then aggregate into the form of columns. These chainlike and columnar structures yield dramatic changes in the rheological properties of the suspensions....
