Electrorheological fluids have been prepared at low applied electric fields from BP oils containing microcrystalline cellulose (MCC); even at a low applied electric field of 500 V mm–1, 10% MCC in oils rich in linoleic or oleic acids behave as electrorheological fluids with the latter displaying significantly higher yield stresses.
