Abstract:

 This study aims to evaluate one of the wastes of the olive oil industry, olive pulp powder OP, due to its consisting of mainly polarizable lignocellulosic biomass, as a dispersed phase in electric field-responsive ER fluid whose rheological properties can be tuned by an externally applied electric field E. The supplied OP was extracted with n-hexane, and structural and thermal analysis revealed the removal of residual oil and soluble small molecules. The OP and n-hexane treated-OP h-OP were dispersed in silicon oil SO, and their rheological and dielectric properties, and dispersion stabilities were investigated. According to the flow test results, the yield stresses τy of both dispersions increased with increasing concentration and the E. The τy of the OPSO and h-OPSO dispersions 25 wt under E3.5 kVmm increased 29 and 130 times greater than their τy values under no E, respectively. The dielectric spectrum analysis showed that enhanced interfacial polarization and decreased nonpolarized forces after the n-hexane extraction improved the ER response of the h-OPSO dispersion. The enhanced dispersion stability 90 was determined for h-OPSO dispersion at 25 wt. As a result, the h-OP could be a sustainable candidate for evaluation as a dispersing phase of ER fluids for vibration-damping systems.
