摘要： An appliance includes a housing defining an interior cabinet, a crisper drawer disposed therein, and a circulation system. The crisper drawer includes a base, walls, and lid defining a cavity, the lid selectively closing the drawer to limit air flow to and from the cavity. One or more of the base, the walls, and the lid define an opening for a humidity membrane disposed therein, sealed in the opening. The membrane includes nanofibers dispersed in a matrix to provide pervaporation across the membrane for airflow from the cavity to the interior cabinet. The circulation system cooperates with the membrane, and includes one or more fans disposed within the drawer to selectively facilitate air flow across the membrane and mix air within the cavity to control a humidity level within the drawer.

摘要： A high-flux composite nanofiltration (NF) membrane with an electrical double layer (EDL) and a preparation method thereof are provided. The high-flux composite NF membrane includes: a charged support membrane and a charged separation layer, where a charge carried by the support membrane or the separation layer is a positive charge, a negative charge, or an amphiprotic charge. The high-flux composite NF membrane with an EDL solves the technical problem that the composite NF membrane in the prior art has an unsatisfactory retention rate and a limited application range due to a small charge quantity.

摘要： The present disclosure provides an article including an isoporous membrane disposed on a porous substrate. The iso-porous membrane includes a triblock copolymer or a pentablock copolymer. The isoporous membrane has a thickness and is isoporous throughout its thickness. A method of making an article is also provided, which does not require a solvent exchange process. The method includes depositing a composition on a porous substrate, thereby forming a fdm, and removing at least a portion of the solvent from the film, thereby forming an isoporous membrane having numerous pores. The composition contains a solvent and solids including a triblock copolymer or a pentablock copolymer. The article advantageously can be hydrophilic and provides sharp molecular weight cut-offs and high flux.
