organic airgel / sherogel / cryogel, process for producing organic airgel / sherogel / cryogel, and, use of xerogels / airgel / cryogels

摘要

functionalized isocyanate-based organic airgel / xerogel / cryogel comprising: - a cross-linked porous network structure consisting of polyurethane and / or polyisocyanurate and / or polyurea, comprising reactive groups on the pore surface thereof ( b) e - functionalizing molecules having a water solubility 10g / l and 20oc chemically linked to the pore surface of the cross-linked porous network structure wherein said molecules have at least one reactive group (a) being capable of binding to the pore. said pore surface (by reaction with groups (b)) and at least one functional group (c) giving the pore surface the desired functionalization.
