    摘要: Present invention relates to a method for forming a nanofiltration hollow fiber membrane comprising a poly(amide-imide) (PAI) hollow fiber substrate having a polyethyleneimine (PEI)-cross-linked PAI surface layer. This membrane is suitable for forward osmosis applications. The method comprises contacting the PAI hollow fiber substrate with an aqueous solution of polyethyleneimine (PEI) under conditions suitable for cross-linking PAI in the surface layer of the PAI hollow fiber substrate by PEI.
