Super‐Amphiphilic Na2Ti3O7 Nanofibrous Film Enabling Water–Oil Miscibility

Due to their extraordinary affinity for both water and oil, super‐amphiphilic materials have garnered considerable interest. A Na2Ti3O7 (NTO) film with super‐amphiphilic properties that enable water and oil miscibility is offered. Multiple nanofibrous 3D porous nanostructures compose the super‐amphiphilic NTO layer. Up to 32–36 times its weight, the film has a high absorption capacity for water and poly‐alpha‐olefin (PAO). The average miscibility ratio of water to oil in the film is ≈6:5. The discovery of NTO nanofibrous film's super‐amphiphilic behavior has significant implications for the development of superwetting materials and their potential applications in the oil emulsion purification and catalyst anchoring industries.
