Abstract
Description
technical field
[0001] The invention relates to the field of materials, in particular to a double-layer porous polymer absorbent that does not leak after adsorption and a preparation method thereof. Background technique
[0002] With the continuous progress of society and the rapid development of industry, waste pollutants are often discharged and produced in the process of industrial production, oil transportation, human activities, natural disasters, etc. These leakage accidents and discharge processes often cause energy loss and environmental threats , and even affect human health, therefore, it is very necessary to find out efficient methods to remove oil and organic pollutants.
[0003] Traditional oil-absorbing materials are mostly inorganic and organic materials that are modified, mixed, and pressed by physical methods. According to their oil-absorbing mechanism, they can be divided into occlusion-type oil-absorbing materials, gel-type oil-absorbing materials, and occ...
