Recently

the contamination of water resource becomes increasingly serious

and how to deal with the oily waste-water is the crucial problem of the environment protection. The high oil-absorbing material is a kind of new functional materials is different from the traditional oil-absorbing material

with excellent performance such as high oil absorption ratio

good selectivity of oil and water and reusable. Developing high oil-absorbing materials has already attracted domestic and foreign researchers' attention. This paper aims at summarizing the research progress of the high oil- absorbing materials

introducing the oil absorption mechanism and all kinds of preparation methods of the high oil-absorbing materials

and gives the developing prospect of the high oil-absorbing materials.
