N-Isopropylacrylamide　(NIPAM)　was　successfully　grafted　on　reduced　graphene　oxide　(RGO)　by　free　radical　polymerization　and　characterized　by　attenuated　total　reflection　Fourier　transform　infrared　(ATR-FTIR)　spectroscopy,　transmission　electron　microscope　(TEM)　measurements,　thermogravimetric　analysis　and　ultraviolet-visible　transmission　spectroscopy.　The　synthesized　poly(N-isopropylacrylamide)-reduced　graphene　oxide　(PNIPAM-RGO)　was　used　to　improve　the　properties　of　polysulfone　(PSF)　membranes　with　different　PNIPAM-RGO　weight　fractions.　The　structure　and　properties　of　PNIPAM-RGO/PSF　membrane　were　characterized　by　X-ray　photoelectron　spectroscopy,　scanning　electron　microscopy,　atomic　force　microscope,　contact　angle　and　tensile　testing.　The　water　permeability,　self-cleaning　recovery　rate　and　water　flux　decline　factor　were　tested.　The　blend　membrane　with　0.4wt%　PNIPAM-RGO　possessed　the　optimal　rejection　and　exhibited　an　impressive　self-cleaning　recovery　rate　and　fracture　strain　of　98.6　and　72.2%,　showing　a　67.4　and　76.5%　enhancement　compared　to　that　of　pure　PSF　membrane　(58.9　and　40.9%),　respectively.　Meanwhile,　the　water　flux　decline　factor　decreased　from　21.0　to　7.8%.　The　drastic　change　of　permeability　to　aqueous　solution,　observed　around　lower　critical　solution　temperature　of　PNIPAM-RGO,　proved　the　thermal　sensitivity　of　the　blend　membrane.　The　NIPAM　grafted　onto　RGO　by　free　radical　polymerization　and　utilizing　the　advantages　of　both　PNIPAM　and　RGO,　which　was　used　as　an　additive　in　the　membrane,　and　very　hard　to　lose　during　the　membrane　formation　and　application.　The　resulting　membrane　exhibited　a　significant　increase　in　self-cleaning　recovery　rate,　hydrophilicity,　mechanical　strength　and　thermosensitivity.
