Abstract

The invention brings forward a hierarchical micro-nanostructure omentum based light-operated oil-water separator and its application method. The oil-water separator comprises an oil-water separator with the hierarchical micro-nanostructure omentum, a constant water surface device, a drainage device, a water gathering device and a light source device. The oil-water separator with the hierarchical micro-nanostructure omentum is composed of an oil-water mixed liquid gathering device and the hierarchical micro-nanostructure omentum, which is made from a pore structured fabric net substrate material with a microstructure and a nanorods array structured material layer which is perpendicular to the surface of the pore structured fabric net substrate material. The hierarchical micro-nanostructureomentum can have superhydrophobicity after dark storage and can have superhydrophilicity by ultraviolet light. The hierarchical micro-nanostructure omentum based light-operated oil-water separator isstable, highly efficient and environmentally friendly. With the application of the light-operated oil-water separator for oil-water separation control, light-operated water can penetrate through the omentum instead of oil. In addition, the light-operated oil-water separator can be repeatedly used.

Description

technical field [0001] The invention belongs to the technical fields of chemical engineering and functional materials, and in particular relates to a light-control oil-water separation device based on a micro-nano hierarchical structure mesh and an application method thereof. Background technique [0002] Controlled wettability of solid surfaces has attracted extensive attention and demonstrated its advantages in solving challenging world problems such as anti-fog, anti-icing, drag reduction, self-cleaning, oil-contaminated water separation, etc. In recent years, the research on the response of solid surface wettability to external stimuli has received extensive attention from researchers, such as light response, electrical response, thermal response, pH response, solvent response, and photoelectric synergistic response. Studies have shown that chemical composition and geometry are the two main factors controlling surface wettability. Micro-nanostructures are often introduc...
