<p>This study investigates the fabrication and performance of magnetically responsive superhydrophobic (MRS) surfaces created by spray-coating a composite of PDMS, carbonyl iron particles (CIPs), and solvent under controlled magnetic fields. The work examines how mixture composition (PDMS-to-CIP ratio, solvent content) and magnetic flux density jointly influence the formation of high-aspect-ratio micro-pillars, where stronger magnetic fields and higher CIP content produce taller and more closely spaced structures. The hierarchical arrangement of pillars contributes to stable air cushions that enhance water repellency and maintain high contact angles even after wetting. Furthermore, re-coating carbon nanoparticles (CNPs) on wetted surfaces restores superhydrophobicity, demonstrating the reconfigurability and durability of the MRS surface. Using external magnets, controlled droplet motion is achieved, with smaller droplets minimizing gravitational effects on sliding behavior. These findings highlight the potential of MRS surfaces for adaptive, reconfigurable liquid control, anti-fouling coatings, and droplet-based microfluidic applications.</p> Graphical abstract <p></p>
