Article Synopsis
- - The study investigates how etching carbonyl iron particles (CIPs) with hydrochloric acid (HCl) improves the coating with 1,2-bis(triethoxysilyl)ethane (BTES) and enhances the stability of magnetorheological fluids (MRFs).
- - Various analyses, including scanning electron microscopy and rheological testing, show that increasing HCl concentration first increases and then decreases nanopores and specific surface area of CIPs, with notable effects at 0.50 mol/L HCl.
- - The findings indicate that optimal etching increases BTES coating mass, affecting the magnetic properties and rheological behavior of MRFs, leading to better shear stress and dispersion stability,
