In the present work, TiO2 films were fabricated on fluorinated ethylene propylene copolymer (FEP) substrates by dip coating of a hybrid sol-gel. The fabricated coating was semi-permeable to allow oxygen diffusion to the eye, transparent so as not to affect visibility, smooth to avoid irritation, possessed sufficient photocatalytic activity to facilitate bacterial destruction.
