静电纺丝复合反渗透膜的改性制备与脱盐性能
Preparation and Desalination Performance of Composite Reverse Osmosis Membrane Based on Electrospinning Technology†
摘要
Abstract
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 inter-facial polymerization was conducted using m-phenylene diamine(MPD) and 1,3,5-benzenetricarbonyl trichlo-ride(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 separa-tion properties. The results showed that the content of SDBS had a certain effect on the uniformity and hydro-philicity 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.关键词
