| With the rapid development of industry and the increase demand for energy, a large number of environmental pollution is inevitably generated in the manufacturing process of civil, industrial and special fields. In order to effectively solve the ecological and environmental problems caused by crude oil spills, the researches on the preparation of superwetting materials, which can separate oil-water mixtures effectively, have become the focus of attention of experts and scholars. The advantages of oil-water separation materials with superwetting properties were summarized, including low cost, high efficiency and simple operation, etc. Meantime, the problem of using routine oil-water separation materials with superwetting properties was outlined. At this stage, a considerable number of common oil-water separation materials could not be recycled or degraded naturally after application. Thus, they were incinerated or directly discarded at last, which caused secondary pollution and harmed the environment easily. Therefore, it is particularly important to build environmentally friendly oil-water separation products from natural and degradable raw materials. As is known to all, cellulose, the renewablely natural polymer material with long history and abundant sources, has good physical properties and special chemical structure, which will be beneficial to the preparation of materials. On that basis, the current status and progress trends of researches on cellulose and its constituent-based superwetting materials, such as the preparation routes, reaction pathways, and oil-water separation applications, have been reviewed importantly. In view of different separation principles, the materials are classified into four categories:superhydrophilic/underwater superoleophobic, superhydrophobic/superoleophilic, superamphiphilic and responsive switching from hydrophilic/hydrophobic to hydrophobic/hydrophilic. The design ideas, forming principles, preparation methods and mechanisms of these kinds of oil-water separation are explained in depth. In recent years, relevant scholars have mainly carried out researches on "water-removing" or "oil-removing" oil-water separation materials based on different preparation principles. The "water-removing" materials are superhydrophilic/underwater superoleophobic and the "oil-removing" materials are superhydrophobic/superoleophilic, which are two fairly important candidates for separating oil-water mixture. The "water-removing" material mainly aims at separating the oil-water mixture of "more oil and less water", removing a small amount of water from the oil phase. The study suggests that most of this kind of the "water-removing" material is required to be prewetted to make the material into a water atmosphere to show the good underwater oleophobicity. It is beneficial to achieving the self-cleaning and improving the oil-water separation efficiency and the reuse rate. The "oil-removing" material mainly aims at separating the oil-water mixture of "more water and less oil". This type of material is easy to be polluted by oil due to the excessive viscosity of crude oil, which reduces the separation efficiency and reuse rate greatly. Likewise, superamphiphilic materials need harsh conditions for the preparation and the complex process, which limits its large-scale preparation and practical application. Besides, responsive switching from hydrophilic/hydrophobic to hydrophobic/hydrophilic materials with switchable oil/water separation performance is expected to be applied in separating oil-water mixture practically. In the process of exploration, it is found that the prospective oil-water separation materials only using greener chemicals in the preparation can meet the requirements of green and sustainable development. The above oil-water separation materials are still in the experimental stage and can not be put into practical use, because there are still some gaps in materials stability and other causes. At last, the opportunities and challenges of cellulose and its constituent-based superwetting materials in oil-water separation are prospected. The further research will still be needed for the practical application of oil-water separation materials. |
