Engineering Research Equipment: Demonstration of Microvalve Operation for Polymer Brush Lined Membranes

科罗拉多大学博尔德分校的伊迪丝·M·塞维克将开发一种测量膜压降和体积流量的装置。该设备包括水泵、流量计、计算机和数据采集软件等外围设备。该装置将被用来研究被吸附了一层聚合物的多孔膜的剪切响应特性。聚合物电刷可能导致一种新型微型阀，这种微型阀将允许在没有机械部件或反馈回路的情况下进行流量控制。将研究聚合物特性和孔径分布的影响。该设备可能会在过滤和其他分离技术以及生物医学设备中得到应用。

CTS-9500413 Edith M. Sevick University of Colorado - Boulder A device will be developed to measure the pressure drop and volumetric flow rate through membranes. The equipment includes a pump, flow meter, computer and data acquisition software and other peripherals. The equipment will be used to investigate the shear response characteristics of porous membranes coated with an absorbed layer of polymer. The polymer brush may lead to a new type of microvalve that will allow flow control without mechanical parts or feedback loops. The effects of polymer characteristics and pore size distribution will be studied. The device may find applications in filtration and other separation techniques, as well as biomedical devices.
