چکیده	Stimuli responsive polymer architectures are attracting a lot of interest, but it still remains a great challenge to develop effective industrial scale strategies. A single-stage and cost-effective approach was applied to fabricate a 3D smart responsive surface with fast and reversibly switchable wetting between superhydrophobicity and superhydrophilicity/underwater superoleophobicity property induced by photo and heat stimuli. Commercially available PVDF and P25TiO2 as starting materials fabricated with a scaled-up electrospinning approach were applied to prepare 3D smart switchable PVDF-P25TiO2 nanotextile super-wetted by both UV and solar light that is simply recovered by heat at a reasonable time. The superhydrophilic/underwater superoleophobic photo-induced nanotextile will act in “water-removing” mode in which the water quickly passes through and the oil is blocked on the surface. An acceptable recycling, reusing, as well as superior antifouling and self-cleaning performance arising from TiO2-photocatalytic effect make it highly desired in green scaled up industry oily wastewater treatment technology. With these advantages, a large scale industrial production process can be simply simulated by applying a conducting mesh-like collector substrate.
