Description
Novel silicone ionomers were synthesized and their particles were dispersed in a silicone oil. The dispersions were evaluated as ER (electrorheological) fluid. (1) Novel silicone ionomers, alkali metal salts of carboxylic acid modified silicone and those of sulfonic acid modified silicone, were developed and particles of these ionomers were made. ER fluids were prepared by dispersing these ionomer particles in a silicone oil. (2) ER fluids made of the carboxylic acid salts type showed high yield stresses over 2 kPa. The yield stresses were the highest at around 100°C. Leak currents increased as the yield stress increased. The properties and the stability at high temperatures were not good. (3) ER fluids made of the sulfonic acid salts type showed low yield stresses, but showed an excellent flat dependency of leak current on temperature. These fluids also showed an excellent stability at high temperatures. The yield stress of these fluids increased as the temperature increased.
