Abstract :In this study, chitosan insert ignore into journalissuearticles values(CS);/expanded perlite insert ignore into journalissuearticles values(EP); composites with different chitosan fractions insert ignore into journalissuearticles values(10%, 20% and 50%); were prepared by absorbing chitosan into porous networks of expanded perlite, as a new hybrid smart electrorheological insert ignore into journalissuearticles values(ER); material. Structural and morphological characterizations of the composites were carried out by FTIR and SEM-EDS techniques. Also, apparent density, particle size, and conductivity of the CS/EP composites were determined. Finally, the effects of electric field strength insert ignore into journalissuearticles values( E );, shear rate, shear stress, and temperature onto ER behavior of the CS/EP/silicone oil system were investigated. The CS/EP/SO ER fluid system showed reversible electrorheological activity when subjected to external electric field strength by showing shear thinning non-Newtonian viscoelastic behavior. The yield stress value reached to 1250 Pa under E = 3 kV/mm for CS/EP3 composite.Keywords :
