The Characterization of Asymmetric Hollow Fiber Membranes using Aqueous Dyes

摘要：GOALI项目涉及下游加工前中空纤维膜的表征。目的是证明使用水性染料来评价聚合物纤维表面孔隙度的可行性。染料吸收测量将与O2/N2渗透数据相关联，以确定该技术是否可以在加工过程中用于预测最终纤维性能。将支持一名研究生在工业地点进行研究。该技术的潜在应用包括工业纤维的生产、多孔表面的分离和表征。

CTS - 9631202 William Koros U of Texas Austin ABSTRACT The GOALI project deals with characterization of hollow fiber membranes prior to downstream processing. The objective is to demonstrate the feasibility of using aqueous based dyes to evaluate the surface porosity of polymeric fibers. Dye uptake measurements will be correlated with O2/N2 permeation data to determine if the technique can be used during processing to predict final fiber properties. A graduate student will be supported to perform the research in an industrial location. Potential applications of the technique include industrial fiber production, separations and characterization of porous surfaces in general.
