第一段:
With the rapid development of economy and the increasing attention people pay on the environment, the separation technology of polysulfone membrane depending on its high efficiency, energy saving, environmental protection, high selectivity and device flexibility, has been widely used in the water treatment of the industrial and agricultural, desalination, biomedical applications and so on. Due to its acid and alkali resistance, anti-oxidation ability, excellent mechanical properties, fitness for using under pressure, polysulfone is always selected as the material of membrane. However, the poor hydrophilicity of polysulfone could easily result in the membrane fouling from biological suspended solids or macromolecules/colloids deposited on the membrane surface and membrane inner holes. Besides, the brittleness and poor flexibility of polysulfone material has limited its application in other fields. |
