    摘要： Provided is an interfacial polymerization process for preparation of a highly permeable thin film composite membrane, which can be used for nanofiltration, forward osmosis, or reverse osmosis, particularly for use with brackish water or seawater. The process includes contacting a porous support membrane with an aqueous phase containing a polyamine to form a coated support membrane, and applying an organic phase containing a polyfunctional acid halide to the coated support membrane to interfacially polymerize the polyamine and the polyfunctional acid halide to form a discrimination layer of a thin film composite membrane, where the aqueous and/or organic phases include a flux-enhancing additive and a boron rejection-enhancing additive that includes a biguanide compound, dicarbonate compound, pentathiodicarbonate compound, or salts thereof. Also provided are the membranes prepared by the methods and reverse osmosis modules containing the membranes.

    摘要： Provided are flux enhancing inclusion complexes for preparing highly permeable thin film composite membranes, and processes that include adding the flux enhancing inclusion complexes to the organic phase or aqueous phase prior to interfacial polymerization of the thin film composite membrane. The thin film composite membranes are suitable for nanofiltration, and reverse and forward osmosis. The provided processes can include contacting a porous support membrane with an aqueous phase containing a polyamine to form a coated support membrane, and applying an organic phase containing a polyfunctional acid halide and a flux enhancing inclusion complex to the coated support membrane to interfacially polymerize the polyamine and the polyfunctional acid halide to form a discrimination layer to form thin film composite membranes.

    摘要： Provided is an antibacterial composition comprising at least one compound including a quaternary ammonium structure having an acrylate group or a methacrylate group, and having an antibacterial strength A of 90% or more against at least one strain selected from Gram-positive bacteria and Gram-negative bacteria, and an acute oral toxicity dose LD50 of 300 mg/Kg or more, where the antibacterial strength A equals (1−Asample/AReference)×100, where Asample equals an absorbance of an inoculated medium solution incubated with the antibacterial composition, and AReference equals an absorbance of an inoculated medium solution incubated without addition of the antibacterial composition.
