Polymer films based on silk fibroin and collagen - the physico-chemical properties
Thin films based on the blend of collagen and silk fibroin were prepared. Biopolymers were dissolved separately in an aqueous solution, mixed together, and after solvent evaporation films were obtained. The surface properties of films have been studied by the contact angle measurements and atomic force microscopy. The mechanical properties such as Young modulus, tensile strength and elongation at break were measured. The results suggest that modification of properties of biopolymeric materials is a consequence of the strong interaction between the polymeric components. The structure and surface properties of two-component blends depend on the mixture composition.
