FACILITATED OLEFIN TRANSPORT COMPOSITE MEMBRANE CONTAINING SILVER NANOPARTICLES USING PEBAX AND METHOD FOR PREPARATION OF THE SAME

摘要

PURPOSE: A high molecule separation membrane for an olefin facilitation transport and a manufacturing method thereof are provided to have excellent transparency and selectivity when being applied in the separation process of various olefins and paraffin and obtain a chemical long stability by polarizing a silver nanoparticle with stabilization by the amide ether group of a high molecule without the adding of other derivatives of both poles like an electron-receptor polarizing the surface of silver nanoparticle partially. CONSTITUTION: A high molecule separation membrane for an olefin facilitation transport has a composite membrane structure comprised of a separation layer and a porous support membrane. A separation layer includes a polyether poly amide block copolymer in which a silver nanoparticle is dispersed on the surface. The separation layer is coated on a porous support membrane. The surface of a silver nanoparticle is polarized by having a positive electric charge by the amide or ether group of the copolymer. The size of the silver nanoparticle is 1-50 nm. The porous support membrane is a plate membrane or a hollow fiber more containing any one porous support selected from metal porous support, and ceramics porous support, a porous support made of polysulfone, polyvinylidene fluoride, poly(amideimide), poly(etherimide), or polyester.
