Abstract[English]
Carrageenan is an attractive bio-derived polymer electrolyte due to its low cost, high ionic conductivity, cyclic stability, and its ability to blend/crosslink with other biocompatible polymers, such as Polyvinyl Alcohol (PVA). Described are the physical and chemical characterization of the bio-electrolyte(s): PVA, carrageenan and PVA-carrageenan bio-polymer blend. A lso described is the fabrication method to create a soft-printed, thin film, bio-gel electrolytic double layer capacitor (Bio-EDLC) using a PVA-carrageenan polymer blend.[French]
Le carraghénane est un électrolyte polymère bio-dérivé attractif en raison de son faible coût, de sa conductivité ionique élevée, de sa stabilité cyclique et de sa capacité à se mélanger/réticuler avec d'autres polymères biocompatibles, tels que le poly(alcool de vinyle) (PVA). L'invention concerne la caractérisation physique et chimique du ou des bio-électrolyte(s) : Le PVA, le carraghénane et le mélange bio-polymère de PVA-carraghénane. L'invention concerne également le procédé de fabrication pour créer un condensateur double couche électrolytique de bio-gel (bio-EDLC) à film mince, d'impression douce, à l'aide d'un mélange de polymères PVA-carraghénane.
