Publication number: 20220184564Abstract: The disclosure relates to a membrane and method for its manufacture, the method including the steps of providing of an ultrafiltration membrane, and modification of the resultant ultrafiltration membrane to provide an asymmetric porous ion exchange membrane. The modification of the ultrafiltration membrane is typically carried out by exposing said ultrafiltration membrane to a first functional reagent to provide a cross-linked ultrafiltration membrane, and then exposing said cross-lined ultrafiltration membrane to a second functional reagent to introduce positive charged groups to produce an anion exchange membrane.Type: ApplicationFiled: March 1, 2022Publication date: June 16, 2022Inventors: Huanting WANG, Xiaocheng LIN

Patent number: 6630696Abstract: Thin films for use as dielectric in semiconductor and other devices are prepared from silica zeolites, preferably pure silica zeolites such as pure-silica MFI. The films have low k values, generally below about 2.7, ranging downwards to k values below 2.2. The films have relatively uniform pore distribution, good mechanical strength and adhesion, are relatively little affected by moisture, and are thermally stable. The films may be produced from a starting zeolite synthesis or precursor composition containing a silica source and an organic zeolite structure-directing agent such as a quaternary ammonium hydroxide. In one process the films are produced from the synthesis composition by in-situ crystallization on a substrate. In another process, the films are produced by spin-coating, either through production of a suspension of zeolite crystals followed by redispersion or by using an excess of the alkanol produced in preparing the synthesis composition.Type: GrantFiled: March 28, 2002Date of Patent: October 7, 2003Assignee: The Regents of the University of CaliforniaInventors: Yushan Yan, Zhengbao Wang, Huanting Wang
