GELLED, CROSSLINKED AND NON-DRIED AQUEOUS POLYMERIC COMPOSITION, AEROGEL AND POROUS CARBON FOR SUPERCAPACITOR ELECTRODE AND PROCESSES FOR PREPARING SAME |
摘要 |
The invention relates to a gelled, crosslinked and non-dried aqueous polymeric composition capable of forming a non-monolithic organic aerogel by drying, to this aerogel, to a non-monolithic porous carbon resulting from a pyrolysis of this aerogel, to an electrode based on this porous carbon, and to a process for preparing this composition and this aerogel. The invention applies in particular to supercapacitors. A gelled, crosslinked and non-dried composition according to the invention, which is based on a resin resulting at least partly from a polycondensation of polyhydroxybenzene(s) R and formaldehyde(s) F and which comprises at least one water-soluble cationic polyelectrolyte P, is such that the composition is formed from an aqueous dispersion of microparticles of a shear-thinning physical gel that is crosslinked in an aqueous medium. The composition not yet crosslinked is in particular prepared by dilution of a prepolymer that forms this gel in an aqueous solvent in order to form the aqueous dispersion of microparticles of said gel. |
