2results about How to "Good fade effect" patented technology

A method for preparing a 2D evaporation membrane constructed from a self-assembled two-dimensional superlattice of molybdate-heteropolyblue subnanowires and its application are disclosed. The method involves dissolving phosphomolybdic acid and transition metal chlorides in a mixed solvent system of oleic acid, oleylamine, and ethanol, stirring at room temperature; then pouring the solution into a stainless steel high-pressure reactor lined with PTFE, reacting, cooling to room temperature, and collecting the solid product by centrifugation; washing, and vacuum drying overnight to obtain molybdate-heteropolyblue powder; dispersing the molybdate-heteropolyblue powder in a cyclohexane-ethanol mixed solution, heating the resulting dispersion, filtering it through a hydrophilic filter membrane to form a membrane, and air-drying it overnight to obtain the 2D evaporation membrane constructed from the molybdate-heteropolyblue two-dimensional superlattice. The advantages are: the nanowire structure of this evaporation membrane provides long-range ordered nanoscale water transport channels, and its internal hydrophilic and external hydrophobic properties enhance water management capabilities, thereby promoting efficient water transport and evaporation, enabling efficient and stable solar thermal seawater evaporation.

The application discloses an integrated sub-nanometer carbon tube graphene oxide reverse osmosis membrane and a preparation method thereof. The reverse osmosis membrane comprises a sub-nanometer carbon tube, a graphene oxide layer and a phospholipid bilayer, the phospholipid bilayer is loaded with the sub-nanometer carbon tube and an integrin, the graphene oxide layer is surface-modified with an anti-adhesion polypeptide, the integrin is bonded with the anti-adhesion polypeptide, the anchoring of the graphene oxide and the phospholipid bilayer is realized, the graphene oxide layer has graphene oxide layer pores and graphene oxide layer interlayer channels, and the phospholipid bilayer is encapsulated in the graphene oxide layer interlayer channels. The reverse osmosis membrane has superior desalination performance, high structural stability and certain pretreatment effect. In the reverse osmosis process, water molecules can quickly pass through, and salt ions cannot pass through, so that high water flux and high desalination rate seawater desalination are realized, and the commercial application purpose of the reverse osmosis membrane seawater desalination is achieved.
