  • Method for the production of hydrogel comprising chitosan and negatively charged polyelectrolytes, and cellular, porous material resulting from said hydrogel
    Patent number: 11168183
    Abstract: The present invention concerns a method for producing a hydrogel comprising the following steps in succession: a first step (i) of providing at least one powder of an anionic polymer (A) and at least one chitosan powder (B) comprising amine functions (—NH2); a second step (ii) consisting in dry mixing at least the powders (A) and (B) from the first step in order to form a mixture of powders; a third step (iii) of suspending the mixture of powders obtained from the second step in an aqueous medium having a pH that can enable the anionic polymer (A) to be dissolved without dissolving the chitosan (B); a fourth step (iv) of adding an acid to the suspension obtained from the third step in order to form the hydrogel; or the third (iii) and fourth (iv) steps are replaced by a mixing fifth step (v), comprising mixing an acidified aqueous medium including at least one compound (C) comprising at least one unit of a hexose or a unit derived from a hexose, and/or at least one phosphate of said compound (C), with said
    Type: Grant
