Abstract

Provided is a method for preparing a polyamide composite membrane which comprises the steps of: forming a polyamide thin film on a porous supporting layer; coating or crosslinking the polyamide thin film surface with a solution of epoxy-silane compounds and drying the resulted membrane; and washing the dried membrane with a basic aqueous solution. Also provided is a polyamide composite membrane prepared thereby.
