Electrospun polyethylene terephthalate(PET) nanofibrous membranes were prepared on the non-woven cloth, then crosslinked chitosan was coated on the composite membrane to modify it. Finally interfacial polymerization was conducted using m-phenylene diamine(MPD) and 1,3,5-benzenetricarbonyl trichloride(TMC) benzene as monomers on chitosan modified nanofibrous to prepare polyamide separation layer. A new type of nanofibrous composite reverse osmosis membrane was obtained. This composite reverse osmosis membrane has typical ridge and valley structure of the typical commercial polyamide composite reverse osmosis membrane. Sodium dodecyl benzene sulfonate(SDBS) content on the properties and structure of the membrane was systematically studied from three aspects, means the film surface morphology, hydrophilicity and separation properties. The results showed that the content of SDBS had a certain effect on the uniformity and hydrophilicity of the membrane morphology. In addition, with the increase of SDBS content, membrane desalination first increases then decreases, and the flux had a small amplitude increase,then it decrease after the increase.
