  • Reverse osmosis composite membrane with an ultrathin desalting layer and preparation method thereof
    Patent number: 12521683
    Abstract: The present disclosure belongs to the technical field of porous membrane material preparation, and specifically relates to a reverse osmosis composite membrane with an ultrathin desalting layer and a preparation method thereof; the intermediate layer is introduced after modifying the polysulfone base membrane, the modified polysulfone base membrane support layer may strengthen the bonding to the desalting layer through a covalent bond, and the thickness of the desalting layer is reduced to be ?10 nm, so that the desalination rate of the membrane is not greatly affected while increasing the membrane flux. Compared with the membrane having a conventional thickness of the desalting layer, the water flux of the reverse osmosis composite membrane with an ultrathin desalting layer may be increased by about 0.5 times, while the desalination rate has a small change.
