Title:
スーパーキャパシタ電極用のゲル化かつ架橋した未乾燥の水性高分子組成物、エアロゲル及び多孔質炭素、並びにその製造方法
Document Type and Number:
Japanese Patent JP6535345
Kind Code:
B2
Abstract:
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.
