Résumé :

Modified chemically crosslinked polyesters as soft and electroconductive materials have investigated for tissue engineering applications. In this work, electroconductivity, thermal stability, and mechanical properties of synthesized Poly (glycerol-sebacate-itaconic) (PGSIT) by the solvent-free method was studied by incorporating polypyrrole (PPy) and clay within the PGSIT matrix. Hydrogen bonds between PGSIT and PPy lead to a homogeneous dispersion of clay and PPy within the PGSIT matrix. The evaluations indicated that PPy and clay could raise the conductivity of PGSIT from 5.9 × 10−11 S/cm to 1.4 × 10−4 S/cm, Young's modulus from 0.19 MPa to 0.9 MPa, tensile strain to 0.91 MPa from 0.25 MPa, and improved the thermal stability and hydrophilicity of the matrix. The PGSIT-PPy-clay composite might have the potential as electroconductive bio-elastomer in tissue engineering applications.
