Abstract

Open-cell foam based on a melamine-formaldehyde condensation product, a polyurethane or a polyimide, which has been modified with hydrophobins, a method of producing such foams, and the use thereof for absorbing organic liquids, as leakage and bleeding protection for liquid stores, for liquid-liquid separation and as matrix for carrying out chemical and/or biological processes.
