biomimetic artificial prostheses which are made from polyester , such as polyethylene terephthalate , and a method for the biomimetic functionalization of such prostheses . the method includes a step involving the grafting of biologically - active polymers or copolymers to the polyester surface of the prostheses , the grafting step consisting of the peroxidation of the surface by ozonation followed by a step including the radical polymerization of a solution of at least one monomer . the method also includes an optional step consisting in impregnating the prostheses with type i and / or ii collagen and / or fibronectins . the prostheses thus obtained enable a normal and uniform regrowth of the fibroblasts , thereby significantly improving the biological integration of such polyester prostheses .
