Porous conductive and biocompatible scaffolds on the basis of polycaprolactone and polythiophene for scaffolding
The fabrication of novel scaffolds was represented on the basis of conductive and biodegradable copolymers. The star-like polycaprolactone (S-PCL) was synthesized from dipentaerythritol as a core by a catalyst of Sn(oct)(8) through ring-opening technique. After functionalization of S-PCL by thiophene, thiophene monomer was polymerized from polycaprolactone ends via chemical oxidation polymerization to reach star-like polycaprolactone-polythiophene (S-PCL-PTh). The scaffolds demonstrated a porous configuration (160-190 nm) having the great surface area as well as conductivity of 0.011 S cm(-1). The cytocompatibility measurements exhibited that the nanofibers were not toxic to the MG63 cells.
