Abstract

Método para producir un hidrogel deshidratado, que comprende los pasos de dispersar fibras en una solución acuosa de un material que es precursor de hidrogel e incorpora un plastificante, incorporando las fibras cationes que son capaces de reticular dicho material precursor para formar un hidrogel, y secar por congelación la mezcla así producida para obtener un hidrogel deshidratado que incorpora dichas fibras, quedando el hidrogel deshidratado reticulado por dichos cationes.
