Dynamic Synergy of Photocatalysis and Hydrophobicity in PDMS-Grafted TiO2 Coatings for Long-Lasting Self-Cleaning
A fundamental conflict in self-cleaning coatings lies in the trade-off between photocatalytic activity (requiring hydrophilic TiO2) and hydrophobic repellency (requiring low-surface-energy polymers). Here, this bottleneck is broken through an in-situ grafting strategy that anchors polydimethylsiloxane (PDMS) chains ont...
