The　potential　of　forward　osmosis　(FO)　for　water　treatment　can　only　be　maximized　with　appropriate　FO　membranes.　In　this　work,　novel　FO　membranes　functionalized　with　hydrophilic　materials　carrying　both　amine　and　sulfonate　or　carboxylate　groups　were　synthesized　via　amidation　reaction　occurred　on　thin　film　composite　(TFC)　FO　membranes.　The　performance　of　the　newly　explored　FO　membranes　was　evaluated　in　FO　desalination　and　antifouling　studies.　Significant　improvement　in　FO　performance　was　observed　for　the　novel　FO　membranes,　in　which　the　water　flux　increases　more　than　19%　for　the　sodium　taurine　(ST)　modified　membrane　(ST-modified　membrane)　relative　to　the　pristine　TFC　FO　membrane　when　pure　water　and　0.5-2.0M　MgCl2　as　the　respective　feed　and　draw　solutions.　Meanwhile,　the　ST-modified　membrane　produced　a　water　flux　33%　higher　than　that　by　the　pristine　TFC　FO　membrane　in　seawater　(3.5　wt%　NaCl)　desalination　with　2.0M　MgCl2　as　the　draw　solution,　drastically　increasing　water　recovery　efficiency.　The　water　flux　decline　of　the　ST-modified　membrane　is　46%　lower　than　that　of　the　pristine　membrane　with　sodium　alginate　as　a　foulant.　Introducing　sulfonate　or　carboxylate　ionic　groups　onto　FO　membrane　surface　is　crucial　to　enhance　the　membrane　antifouling　ability　and　thus　improves　FO　performance,　which　provides　new　insight　in　novel　FO　membrane　exploration.
