Electrorheological fluids consist of polarizable particles in an insulating media. Particle formation upon application of an electrical field characterizes electrorheological mechanisms. Different problems associated with these fluids include dispersion stability, durability, corrosion, abrasion, and a limited temperature range in use. The use of chitosan derivatives based on a natural biocompatible polymer as the organic disperse phase solves these problems. Chemical reactions between chitosan and succinic acid under catalysis synthesize chitosan succinate for use as the organic disperse phase. Measurements of chitosan succinate in silicone oil include electrical and rheological properties. Chitosan succinate suspensions provide an electrorheological performance under an electrical field due to the polarizability of the branched amide group. 12 refs.
