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.

CTS - 9631202 William Koros U德克萨斯州奥斯汀 摘要 GOALI项目涉及中空纤维膜在下游加工之前的表征。 目的是证明使用水基染料来评估聚合物纤维的表面孔隙率的可行性。 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场所进行研究。 该技术的潜在应用包括工业纤维生产、多孔表面的分离和表征。
