This paper reviews the research progress of membranes based on the principle of superhydrophilicity and superoleophobicity and its application in the oil-water separation. First

the fundamentals of the research are introduced

including those for preparing superhydrophilic and superoleophobic membranes and separation process

basic properties of membranes and influencing factors. The applications of liquid bridge principle in the superhydrophilic and superoleophobic membranes

membranes structures

general raw materials and prepared methods are also introduced. Then a comprehensive overview is given on the research progress of current common types of membranes

mainly including the stimuli-responsive superhydrophilic and superoleophobic membranes

superhydrophilic and underwater superoleophobic membranes

inorganic crystalline nanowires superhydrophilic and superoleophobic membranes

molecular brush structure superhydrophilic and superoleophobic membranes

and membranes for effective separation of oil-in-water emulsions. Finally

some problems in the current research area are advanced

including the basic theory of membrane separation

raw materials of membrane

membrane flux

membrane life

range of application

etc.

and the development trends are prospected.
