Beschreibung
Zusammenfassung:	A polyamino acid gel material. The material is prepared by performing a pre-crosslinking treatment on an endogenous polyamine and a polyamino acid under the action of an activator, then freezing and crosslinking same, then thawing same at room temperature, and cyclically repeating the freezing-thawing process 0-3 times so as to obtain a polyamino acid gel material, wherein the polyamino acid is a polyglutamic acid or polyaspartic acid, and the endogenous polyamine is spermine or spermidine. L'invention concerne un matériau de gel d'acide polyaminé. Le matériau est préparé par mise en oeuvre d'un traitement de pré-réticulation sur une polyamine endogène et un acide polyaminé sous l'action d'un activateur, puis congélation et réticulation de celui-ci, puis décongélation de celui-ci à température ambiante, et répétition cyclique du processus de congélation-décongélation de 0 à 3 fois de façon à obtenir un matériau de gel d'acide polyaminé, le polyaminoacide étant un acide polyglutamique ou un acide polyaspartiqu
