• • The SiO2 'bridge' layer enables grafting of PDMS brushes onto shape memory epoxy, achieving low adhesion to liquids with surface tensions as low as ~20 mN/m, overcoming limitations of superhydrophobic surfaces that only repel high-surface-tension liquids.
• • Precise control of SiO2 layer thickness and grafting conditions yields surfaces with both shape memory and quasi-liquid properties, enabling reversible anisotropic/isotropic droplet sliding control for water and organic droplets.
• • The coating demonstrates anti-fouling and self-cleaning properties on diverse substrates, with potential for applications requiring durable, low-maintenance surfaces.
• • The combination of shape memory polymer and PDMS brushes offers programmable droplet manipulation, addressing the issue of lubricant loss in SLIPS and structural fragility in superhydrophobic surfaces.
