Multifunctional magnetorheological elastomers with superior superhydrophobicity and mechanical robustness enabled by magnetic alignment

• Magnetically guided sharkskin MRE yields a robust superhydrophobic surface. • Retains WCA > 150° after 500 cm abrasion via self-regenerating superhydrophobicity. • Stable to water-jet shear and 90-day open-air exposure. • Compressive strength increased 59% due to magnetically aligned microchains. • SHIP incorporation and magnetic curing enhanced shear storage modulus and loss factor of SHS. Superhydrophobic surfaces (SHS) promise multifunctional performance, but practical use is often limited
