An ESCA study of new collagen-based bioartificial polymeric materials

The surface composition of films prepared from blends containing different percentages of pure soluble collagen and poly(acrylic acid) or poly(sodium vinylsulfonate), was analysed by ESCA. The results indicate that the content of collagen on the surface of the blends is higher than expected, and tha...

Description
Summary:The surface composition of films prepared from blends containing different percentages of pure soluble collagen and poly(acrylic acid) or poly(sodium vinylsulfonate), was analysed by ESCA. The results indicate that the content of collagen on the surface of the blends is higher than expected, and that such enrichment is more evident for the blends containing a lower percentage of collagen.
