摘要： Certain aspects of the invention relate to a method of synthesizing a composite usably for oil-water separation comprising surface nanostructuring a pristine powder or porous material to form a nanostructured powder or porous material having surfaces with nanoscale features; and coating single or multilayers of one or more low surface energy oligomers, polymers, or their composites with other materials on the surfaces of the nanostructured powder or porous material.

摘要： Certain aspects of the invention relate to a composite for oil-water separation, synthesis methods and applications of the same. The composite includes a nanostructured powder or porous material having surfaces with nanoscale features, formed from a pristine powder or porous material by a surface nanostructuring process, and single or multilayers of a low surface energy oligomer or polymer coated on the surfaces of the nanostructured powder or porous material. The composite is hydrophobic (or superhydrophobic) and oleophilic (or superoleophilic) operably repelling water and absorbing oil, or oleophobic (or superoleophobic) and hydrophilic (or superhydrophilic) operably repelling oil and absorbing water.
