Surface Modification: Self cleaning, anti corrosion, anti bacterial, impact resistance

Works have been accomplished…

• Modify glass surface: Fabrication of novel hydrophobic, superhydrophobic, and oleophobic layers

• No compromising on glass transparency

• Facile coating methods: One-pot “grafting to” methodology using “thio-bromo click” chemistry

• Controlled polymerization of hydrophobic monomers in water
