Abstract
The present invention concerns the preparation of composite biomaterials constituted by hyaluronic acid and the derivatives thereof in combination with polymers that have electrically conductive properties. In particular, the methods of preparing biomedical devices formed by a two- or three-dimensional polysaccharide matrix and by an electrically conductive membrane. The matrix is constituted by hyaluronic acid derivatives in the form of membranes, woven fabrics, nonwoven felts, meshes, gauzes, guide channels or sponges, while the electrically conductive membrane is constituted by a film of polypyrrole (polymer conductor) in combination with hyaluronic acid or a derivative thereof (doping agent).
