Abstract
The present disclosure provides a porous material having a surface that is concurrently both superhydrophilic (having a first apparent advancing dynamic contact angle of less than or equal to about 5° for water) and oleophobic (having a second apparent advancing dynamic contact angle of greater than or equal to about 90°) or superoleophobic (a second apparent advancing dynamic contact angle of greater than or equal to about 150° for oil). Such materials can be used in a separator device to separate a liquid-liquid mixture of immiscible components (e.g., oil and water) or miscible components (e.g., alcohols). Separation apparatus incorporating such materials and methods of making and using these materials are also provided.
