Electroresponsive Performances of Ecoresorbable Smart Fluids Consisting of Various Plant‐Derived Carrier Liquids

Abstract

This paper proposes the fabrication of a new type of electrorheological (ER) fluid with ecoresorbable features as well as excellent electroresponsive performance. The proposed ER fluid consists of biocompatible Mg‐doped silica/titania hollow nanoparticles (ST HNPs) suspended in vegetable oils (canola, grapeseed, olive, and soy). The effects of biodegradable plant‐derived carrier liquids on the ER performance are analyzed. The polarizability and wettability of the fabricated ER fluids are studied. The high polarizability of the nanoparticles contributes to the highly electroresponsive performance by inducing electrostatic interactions between the nanoparticles under electric fields; this enables the formation of a rigid and strong fibril structure. A suitable wettability, which represents the favorable interaction between the oil and the nanoparticles, allows the nanoparticles to disperse evenly in the oil and prevents their aggregation, thereby making the formation of a rigid and strong fibrillar structure under the electric field easier.

“…[44][45][46] Moreover, such fluids show stable response in a wide temperature range which is of great importance for real practical application. 47 The natural oils and fillers allow to create completely eco-friendly ERFs, [48][49][50] so polysaccharides are promising candidates from this point of view as well. 51,52 One of the ways to increase the electrorheological response is to change the electrophysical characteristics of the filler with surface modification or doping.…”
