The prepared three-dimensional block oil-water separation material generally has layered macropores and mesopores, so that the transportation of macromolecules is easier due to the characteristic that the prepared three-dimensional block oil-water separation material can effectively utilize the mesopores and micropores connected by a macroporous system, and the transmission efficiency is improved. However, the research on the oil-water separation material with a three-dimensional network porous structure still has some problems, such as complicated preparation process, complicated sample drying process, high cost, unfavorable industrial production, poor thermal stability and certain environmental pollution caused by the adopted chemical reagent. Therefore, how to realize the mass production of the oil-water separation material with a three-dimensional network porous structure by a practical and economic method is still a challenge.

Preferably, the oil-water separation material is a three-dimensional net structure, and the mesh size of the net structure is 20-150 μm. The adsorption effect is dependent on the number and size of the pores of the material, i.e. the pore volume, the greater the total volume, the better the adsorption effect.
