摘要： Electrospun poly(acrylic) acid (PAA)/poly(vinyl) alcohol PVA nanofibers and integrated filtration membranes generated therefrom are disclosed herein. The membranes are suitable for use in selectively removing heavy metals such as lead and cadmium from water. The surface of the nanofibers is preferably functionalized with one or more chelating agents. The membranes have a high removal efficiency and adsorption capacity with well-distributed high-density heavy metal adsorption sites with strong binding affinities for targeted heavy metals.

摘要： A crosslinkable copolymer is provided. The crosslinkable copolymer has pendant cationic nitrogen-containing groups with some, but not all, of these pendant groups further including a (meth)acryloyl group. The (meth)acryloyl groups can react to form a crosslinked copolymer that is ionically conductive. The crosslinked copolymer can be used to provide an anion exchange membrane that can be used in electrochemical cells such as fuel cells, electrolyzers, batteries, and electrodialysis cells.

摘要： A novel thermo-induced stimuli-responsive membrane for leukocyte enrichment and its application to white blood cells were disclosed. Specifically, the thermo-induced stimuli-responsive membrane for leukocyte enrichment comprises a layer coated on a porous substrate, and composition of the layer comprises at least one copolymer selected from one of group consisting of poly(acrylic acid-co-alkyl methacrylate), poly(N-alkyl acrylamide-co-alkyl methacrylate) and their mixture. In particular, the time for white blood cells recovery is within 1 hour, so as to obtain fresh and high purity white blood cells by using the novel thermo-induced stimuli-responsive membrane.
