    摘要： Polymeric surfactants (molecular micelles) are disclosed for use in open tubular capillary electrochromatography or in high performance liquid chromatography. For example, fused silica capillaries are coated with thin films of charged polymers in a polyelectrolyte multilayer (PEM). A PEM coating may be formed in situ by alternate rinses with positive and negative polyelectrolytes. At least the innermost of the negatively charged polymer layers is a molecular micelle. Prototype embodiments have successfully separated seven benzodiazepines from one another. The run-to-run, day-to-day, week-to-week and capillary-to-capillary reproducibilities were very good, with relative standard deviation values less than 0.01. The PEM-coated capillary was very robust over at least 200 runs. Stability against high and low pH values was also observed. Using chiral polymerized micelles, chiral separations may be achieved, as was demonstrated with a separation of the enantiomers of 1,1′-binaphthyl-2,2′-dihydrogenphosphate. Alternatively, layers for use in this invention may be formed from zwitterionic polymers in lieu of separate cationic and anionic layers. Zwitterionic polymer layers may be used either with or without molecular micelles.

    摘要： A method is described for producing an osmotically compacted polyelectrolyte complex having a first region and a second region, the first region having a greater modulus than the second region. The method comprises contacting an article comprising polyelectrolyte complex to a solution comprising a preferred osmolyte of concentration sufficient to compact said polyelectrolyte complex and terminating the compaction process before the entire article is osmotically compacted.A method is also described for producing a article comprising water and an intermolecular blend of at least one positively charged polyelectrolyte polymer and at least one negatively charged polymer, said article having a core region and a surface region, the surface region having at least twice the elastic modulus of the core region, the method comprising contacting a starting article comprising a blend of said polymers with a solution of osmolyte, wherein the osmolyte is excluded from said article.

    摘要： A membrane comprising two or more macromolecules that interact via multiple reversible physical interaction points (MRIPM). The membrane further comprises a chemical species A, which interacts selectively or nonselectively with the MRIPM; and a chemical species B, which interacts selectively with the MRIPM whereby the passage of species A across the MRIPM is moderated by species B.
