SUPERHYDROPHILIC AND OLEOPHOBIC POROUS MATERIALS AND METHODS FOR MAKING AND USING THE SAME

摘要

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.
