1. A method of synthesizing a biomaterial cross-linked urethane-doped polyester polymer comprising the steps of:

  • combining at least one multi-functional monomer comprising at least 2 carboxyl and at least one diol to form a polyester polymer;

    adding one or more di-isocyanate monomers to the polyester polymer to form a urethane doped polyester; and

    forming ester-bond crosslinks between the urethane doped polyester through the condensation of the side carboxyl groups and hydroxyl groups on the polyester polymer chains to form a crosslinked urethane doped polyester polymer network with one or more urethane/urea bonds doped in the polyester chains between the ester-bond crosslinks.
