Abstract
The electrorheological behavior of the glucosamine and glucosamine hydrochloride suspensions was investigated. The the glucosamine suspension behaved as a Newtonian fluid due to low conductivity even though it has polar group. The glucosamine hydrochloride suspension behaved as a Nonnewtonian fluid under the application of the electric field. The shear stress of the glucosamine hydrochloride suspension is proportional to 1.86 power of the electric field. The value of the structure factor, $A_s$ was 1 and it may be resulted due to the formation of single chain upon application of the electric field.
