THIN FILM COMPOSITE MEMBRANES FOR PERVAPORATION

摘要

Disclosed is a thin film composite membrane that includes a ceramic support having a thickness of 1 to 10000 µm and a pore size of 1 to 200 nm, a polymeric gutter layer having a thickness of 1 to 10000 nm and bonded covalently or non-covalently onto the ceramic support, and a thin film layer having a thickness of 10 to 1000 nm and bonded covalently onto the polymeric gutter layer. Also disclosed are methods of preparing the above-described thin film composite membrane.
