Abstract
In various aspects, the present disclosure provides porous materials having extreme wettability to polar or non-polar fluids, such as water and oil. The porous material has a coated surface comprising a low surface energy fluoroalkyl silane that is treated to exhibit at least one type of extreme wettability. In certain aspects, the disclosure provides a porous material comprising a coated surface that is both superhydrophobic and oleophilic, or superhydrophobic and superoleophobic, or superhydrophilic and oleophobic, by way of example. Methods of forming a porous surface having a predetermined wettability are also provided. Other embodiments include fluidic devices that incorporate porous materials having extreme wettabilities, such as microfluidic devices and separators.
