Swelling and Plasticity of Polyelectrolyte Complexes of Collagen Hydrolysate Carboxymethyl-Cellulose

Research focused on swelling and plasticity of films of polyelectrolyte complexes of collagen hydrolysate-carboxymethyl cellulose. Objects under study were influence of various stabilisation mode (cross-linking by dehydration or with glutaraldehyde), swelling liquid pH and its ionic strength. Plasticity of complexes was evaluated through isotonic measuring of swelled film compressibility. The test enabled to determine total deformation as well as its elastic and permanent component. Swelling and plasticity of films of polyelectrolyte complexes were mainly affected by network density. Complexes were prepared whose swelling ranged from 300 up to 2500% depending on mode of stabilisation. Together with network density, which was determined from swelling of complexes, there is an increase in ideal elastic deformation, possibly attaining as much as 70% total deformation.
