ATTRACTING FORCE-ADJUSTABLE MATERIAL, METHOD FOR PRODUCING THE SAME, AND ELECTRO-RHEOLOGICAL ELEMENT

摘要

PROBLEM TO BE SOLVED: To provide an attracting force-adjustable material which can be reformed into a desired shape after it has been formed once. SOLUTION: The attracting force-adjustable material comprises electro-rheological particles dispersed in an electric insulating medium containing crosslinked hydrogensilicone. The electric insulating medium has stress of 0.20 N or less measured at a plunging speed of 1 mm/sec using a probe tack tester. The attracting force-adjustable material is characterized in that an inclination angle between the electric insulation medium surface and the vertical surface after a cylindrical container with a diameter of 30 mm and a height of 35 mm has been filled up with the electric insulting medium up to 15 mm beneath the top surface of the container and 24 hours have passed after the container has been overturned by 90 degree is less than 20 degree.
