PURPOSE:To provide an electroviscous fluid-holding non-sedimentary porous form having stable electroviscous fluid characteristics for a long period of time without impairing its performance, and to provide an electroviscous fluid- applied device having the above porous form. CONSTITUTION:The porous form characterized by consisting of a flexible open cell-type porous form such as non-membrane polyurethane foam, having specific pore size, impregnated with an electroviscous fluid composed of disperse phase powder such as carbonaceous powder and electrically insulating oil, and the other objective electroviscous fluid-applied device provided with this porous form. |
