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.
