Abstract

Provided herein is a prohealing piezoelectric coating and the method of making and using the same.

Claims

exact text as granted — not AI-modified
What is claimed is: 
     
         1 . A method of generating piezoelectric polarization in a coating on an implantable device, comprising:
 forming the coating comprising a piezoelectric polymer(s) onto the implantable device,   providing solvent vapor to the coating,   subjecting the coating to high electric voltage to generate polarization of the piezoelectric polymer(s), and   removing the solvent vapor from the coating and causing the coating to dry, thereby fixing the polarization of the piezoelectric polymer(s) in the coating.   
     
     
         2 . The method of  claim 1 , wherein the piezoelectric polymer comprises units derived from fluoro vinyl monomers. 
     
     
         3 . The method of  claim 1 , wherein the piezoelectric polymer is selected from PVDF, PVDF-TrFE, PVDF-TFE, or combinations thereof. 
     
     
         4 . The method of  claim 1 , wherein the piezoelectric polymer comprises PVDF-HFP. 
     
     
         5 . The method of  claim 1 , wherein the solvent is acetone. 
     
     
         6 . The method of  claim 1 , wherein the coating further comprises at least one bioactive agent.
