A　superhydrophilic　poly　(ethyleneimine)/poly　(acrylicacid)　PEI/PAA-Cerium　carbonate　(Ce-2(CO3)(3))　composite　membrane　was　fabricated　through　layer-by-layer　(LbL)　self-assembly　and　in　situ　mineralization　of　Ce-2(CO3)(3).　The　surface　structures,　wetting　behavior　and　NF　performance　of　the　membranes　were　investigated.　The　results　indicated　that　the　water　contact　angle　of　[PEI/PAA-Ce-2(CO3)](3.0)　membrane　decreased　with　increasing　incorporated　Ce-2(CO3)(3)　content.　Under　0.025　mol/L　of　Ce-2(CO3)(3)　content,　the　prepared　membrane　showed　superhydrophilic　surface　with　water　contact　angle　of　3.1　degrees,　which　can　effectively　separate　methyl　blue,　xylenol　orange　and　eriochrome　black　T　from　aqueous　solution　with　rejection　of　more　than　95%　and　flux　of　more　than　152.0　L/m(2)　MPa　h,　respectively.　In　addition,　the　superhydrophilic　membrane　showed　better　long-term　running　stability,　and　antifouling　property.　After　3　cycle　of　running　and　cleaning,　the　flux　recovery　rate　was　about　85%,　and　the　irreversible　flux　decay　rate　was　14.53%.　Moreover,　the　Derjaguin　Landau　Verwey　Overbeek　(XDLVO)　approach　further　demonstrated　that　the　superhydrophilic　membrane　showed　higher　antifouling　property　than　the　hydrophilic　one.　(C)　2018　Taiwan　Institute　of　Chemical　Engineers.　Published　by　Elsevier　B.V.　All　rights　reserved.
