1、Graphene Oxide Membrane A Kind of Membrane Materials,Part Introduction about General Membranes Part Graphene Oxide Membrane,What is Membrane?,PET(polyethylene terephthalate)聚对苯二甲酸乙二酯 PE(polyethylene)聚乙烯 PVC(Polyvinyl chloride)聚氯乙烯,“Water cube“ is one of the worlds largest membrane structure works. I
2、n addition to the ground, the outside surface of the membrane structure has been adopted ETFE materials. The blue outside surface is surprisingly soft but very substantial. ETFE（Ethyl Tetra Fluoro Ethylene）四氟乙烯,If the outside surface of the “Water cube“ brokes a hole, it will become as well as befor
3、e only with adhesive stickers. The structure of the membrane is very light. It has good performance of self-cleaning. The dust is not easy to stick on the surface can be washed away by rain.,SoWhat is membrane? Membrane is materials that have ability of selective separation. Membrane has different a
4、pplications with different hole sizes. The most important character： Selective separability.,Separation Mechanism of Membranes,Graphene oxide(GO) is the oxide of graphene. It Has a single atomic layer, so its thickness is only 0.335nm. It is the thinnest nano materials but has the biggest intension. Its color is brown and its products are often powder, flake or solution commonly on the market.,Preparation,Morphology,Morphology under TEM,If graphene oxide is doped in PSF (polysulfone), the membrane may look like this.,Liquid Separation,Gas Separation,Thank you！,
