摘要: A method of preparing a filtration membrane. The method includes providing a copolymer solution by dissolving a statistical copolymer in a mixture of a co-solvent and a first organic solvent, coating the copolymer solution onto a porous support layer to form a polymeric layer thereon, coagulating the polymeric layer on top of the support layer to form a thin film composite membrane, and immersing the thin film composite membrane into a water bath to obtain a filtration membrane. Also disclosed are a filtration membrane prepared by the method and a process of filtering a liquid using the filtration membrane thus prepared.

摘要: A method for producing an asymmetric porous membrane includes: forming a first casting film from a casting solution on a carrier, the casting solution containing a hydrophobic polymer, a hydrophilic polymer, a water-soluble polymer, and a solvent; placing the first casting film in an environment containing water vapor to contact the first casting layer with the water vapor, thereby obtaining a second casting film, the environment having a temperature ranging from 20°C to 33°C and a relative humidity of 30% to 80%; and contacting the second casting film with a coagulating agent so as to perform a wet-phase inversion. The hydrophilic polymer is polyvinylpyrrolidone, polyalkylene glycol, or a combination thereof. The water-soluble polymer is a copolymer of vinylpyrrolidone and vinyl acetate, a copolymer of vinylpyrrolidone and alkylene glycol, a vinyl alcohol-based polymer, an ethylene glycol/propylene glycol based copolymer, an ethyleneimine-based polymer, a water-soluble cellulose, or combinations thereof.
