Swelling behavior of hyaluronic acid/polyallylamine hydrochloride multilayer films.

摘要: The reversible swelling behavior of multilayer films containing hyaluronic acid and polyallylamine hydrochloride was investigated using in situ ellipsometry, since many the natural functions applied uses are related to extraordinary ability this biopolymer swell, respond conformationally local solution environment. This observed be substantial, depended strongly on film thickness, pH conditions used prepare films, ionic strength. results were also rationalized terms dissociation polyelectrolytes assemblies, measured by ζ potential, colloidal particles. found swell as much 8 times their dry extent hydration depend thickness a nonlinear fashion. internal structure which is dictated assembly co...
