  • Publication number: 20160164139
    Abstract: The invention relates to a monolithic ionogel with an organic confinement matrix for at least one ionic liquid, and a method for manufacturing same. An ionogel according to the invention comprises a biopolymer confinement matrix with a cross-linked polysaccharide base and an ionic liquid confined in a network formed by the matrix, and it is such that the polysaccharide has siloxane cross-linking bridges, the ionogel being a chemical gel able to constitute a self-supported solid electrolyte by itself. This ionogel is obtained using a method comprising silanisation of the polysaccharide in a basic aqueous solution by a silanisation agent, and polycondensation of the silanised polysaccharide. In a first embodiment, this method comprises preparing a hydrogel with a polysaccharide base that is silanised and cross-linked by sol-gel, then exchange reactions of solvents with increasing hydrophobicities.
