Process for producing porous materials

Abstract

A porous material is prepared mixing at least one bio-based polymer and at least one polyionic biopolymer and water, in an aqueous solution of a polyvalent metal ion to prepare a gel, exposing the gel to a water-miscible solvent to obtain a gel, and drying of the gel. The porous material obtained in the method finds application as thermal insulation material, as carrier material for load and release of actives, for electrode materials in batteries, fuels cells or electrolysis, for catalysis, for capacitors, for consumer electronics, for building and construction applications, for home and commercial appliance applications, for temperature-controlled logistics applications, for vacuum insulation applications, for battery applications, for apparel applications, for food applications, for cosmetic applications, for biomedical applications, for agricultural applications, for consumer applications, for packaging applications or for pharmaceutical application or as carrier materials or adsorbents.
