The degree of adsorption of chitosan on the collagen matrices of bovine pericardium upon deposition from solutions in the two-phase H2O/CO2 system was studied as a function of pressure.
The effect of the clathrate hydrate environment in the water/carbon dioxide system on the structure of the chitosan-coated collagen xenograft tissue was demonstrated. The collagen xenograft tissue treated in this environment is a porous material with a pore size of 50–500 nm having also micrometer size (1–3 μm) pores. The high porosity results in averaging of the structural organization features in...
