COMPOSITE MEMBRANE, METHOD OF MANUFACTURING THE SAME, SEPARATION MEMBRANE INCLUDING THE COMPOSITE MEMBRANE, AND WATER TREATMENT DEVICE USING THE SEPARATION MEMBRANE

摘要

An organic/inorganic composite membrane may include hydrophilic inorganic particles dispersed in an organic polymer matrix having finger-like pores. The hydrophilic inorganic particles may be present at a higher concentration near one surface of the membrane having a higher density than the other surface of the membrane having a lower density.
