Piezoelectric Conductive Composite Stent And Preparation Method Thereof

Abstract

The present invention provides a piezoelectric conductive composite stent and a preparation method thereof, the length of the piezoelectric conductive composite stent is 1 cm-3 cm, the inner diameter of the piezoelectric conductive composite stent is 2.5 mm-3.5 mm, and the thickness of the pipe wall of the piezoelectric conductive composite stent is 0.4 mm-0.45 mm. The piezoelectric conductive composite stent comprises: an inner layer and an outer layer sleeved outside the inner layer, and a plurality of nano grooves are provided in the peripheral face of the outer layer; wherein, the inner layer is prepared from polycaprolactone dissolved in a binary organic solvent; the outer layer is prepared from at least one of the polycaprolactone dissolved in a binary organic solvent, polyvinylpyrrolidone dissolved in a binary organic solvent, nanoparticles of metal organic framework materials, or nanoparticles of graphene or its derivatives.
