The　developments　of　metal　organic　framework　(MOF)/polymer　hybrid　membranes　are　hampered　by　the　problems　of　MOF　particles　agglomeration　and　harsh　synthetic　conditions　of　MOFs.　In　this　paper,　we　provide　a　facile　and　simple　route　for　fabrication　of　a　uniform　MOF/polymer　hybrid　membrane　via　the　combination　of　self　assembly　and　interfacial　reaction　method.　The　positive　charged　polyethyleneimine　(PEI)　molecules　and　zinc　ions　were　first　deposited　on　the　negative　charged　hydrolyzed　polyacrylonitrile　(HPAN)　substrate　via　electrostatic　attraction　(self-assembly),　and　then　zeolitic　imidazolate　framework-8　(ZIF-8)　particles　were　in-situ　formed　in　a　polyethyleneimine　(PEI)　layer　via　interfacial　reaction,　thereby　forming　a　thin　and　uniform　ZIF-8/PEI　hybrid　membrane.　The　prepared　membrane　possessed　a　rejection　of　99.6%　for　methyl　blue　aqueous　solutions,　with　permeance　up　to　33.0　L　m(-2)　h(-1)　bar(-1).　These　results　suggested　that　the　ZIF-8/PEI　hybrid　NF　membrane,　which　was　prepared　under　facile　conditions　without　any　complex　post-treatment,　can　be　a　promising　candidate　for　dye　removal　process.
