Robust superhydrophilic polylactide (PLA) membranes with a TiO 2 nano-particle inlaid surface for oil/water separation

To overcome the surface instability of traditional polymeric membranes especially with superwetting behaviour, a robust superhydrophilic surface was fabricated with nano-TiO 2 inlaid on a hierarchical polylactide (PLA) ultrafiltration membrane via a spin coating process.
