Poly(aspartic acid) Biohydrogel as the Base of a New Hybrid Conducting Material

Abstract

In the present study, a composite made of conducting polymer, poly(3,4-ethylenedioxythiophene) (PEDOT), and a biodegradable hydrogel of poly(aspartic acid) (PASP) were electrochemically interpenetrated with poly(hydroxymethyl-3,4-ethylenedioxythiophene) (PHMeDOT) to prepare a new interpenetrated polymer network (IPN). Different cross-linker and PEDOT MPs contents, as well as different electropolymerization times, were studied to optimize the structural and electrochemical properties. The properties of the new material, being electrically conductive, biocompatible, bioactive, and biodegradable, make it suitable for possible uses in biomedical applications.

Recent Progress in Biomedical Sensors Based on Conducting Polymer Hydrogels

“…This resulted in the formation of a poly­(hydroxymethyl (3,4-ethylenedioxythiophene)) (PHMEDOT) network through the polymerization of the HMEDOT monomers and interconnection with the PEDOT particles. Similarly, a polyaspartic acid hydrogel was used as a base to obtain a conductive IPN hydrogel by loading PEDOT NPs and the subsequent in situ electropolymerization of PHMEDOT . In another work, an IPN was fabricated based on PANI and poly­(acrylamide- co -sodium acrylate) (ASH).…”
