摘要：
This invention relates to the preparation of, and a device for using, a permanently deformed sulfonated halopolymer article. A flexible and non-brittle flange may be formed from at least one end of a hollow perfluorosulfonic acid membrane in one aspect of the invention. The flanged membrane is particularly useful for quick attachment and detachment to various instrumentation used for pervaporation. In addition, by packing the membrane with a means for increasing radial diffusion of fluid within the membrane, pervaporation efficiency may be increased.
