In the present study, the results of viscosity measurements in dilute solutions of chitosan (Ch) with hyaluronic acid (HA) are presented. Chitosan is blended with hyaluronic acid in aqueous 0.1M CH3COOH/0.2M NaCl and 0.3M NaCl respectively, or with the addition of HEPES. Viscosity measurements of dilute polymer solution were carried out in an Ubbelohde capillary viscometer. The intrinsic viscosity, [], and the viscosity interaction parameters, bm, have been determined for the binary (solvent/polymer) and ternary (solvent/polymer A/polymer B) systems. The homogeneity and morphology of chitosan blends were ascertained from the tapping-mode atomic force microscopy. The surface roughness of chitosan, hyaluronic acid and Ch/HA blended films was altered by mixing. The obtained results suggested that there was existence of the strong interactions between chitosan and hyaluronic acid.
