Abstract

The present invention provides dopant-free conductive elastomeric polyurethanes that have broad biomedical application, including smart drug delivery, electronics and biomedicine. In various embodiments, a dopant-free conductive, elastomeric polyurethane is designed by covalently conjugating biodegradable segment, conductive segment and dopant molecule into one polymer chain. The dopant-free conductive polyurethanes according to various embodiments of the invention exhibit attractive mechanical properties, including bending, knotting, stretching and recoiling. The biodegradable, conductive elastomer also exhibit good electroactivity and electrical stability without extra dopant involvement.
