Abstract: A textile fabric for preventing the penetration and water spreading in cables, having at least one layer, which is at least partially covered by an absorbent material and has pores, which pores can be at least partially closed under the effect of liquid due to absorbent material swelling, the absorbent material being bonded to the textile layer, at least in some areas, has a DIN ISO 9073-3 tensile strength in machine direction of >50 N/5 cm, and obtainable by a method involving: treating a layer containing pores with a mixture containing a polymerizable monomer or oligomer and a cross-linking agent and, as absorbent material precursor, a wetting agent and initiator, and polymerization of the monomer or oligomer under formation of a bonded connection between the absorbent material and the layer. The textile fabric can have a DIN EN ISO 9237 air permeability in dry state of greater than 200 dm3/(m2s).

Abstract: A separator for at least one of electrochemical energy accumulators or converters includes: a porous substrate with a comb polymer, the comb polymer containing a polymer main chain along several lateral chains that are covalently bonded to the polymer main chain. At least one of the lateral chains has at least one Lewis-acid or Lewis-base functionality.

Abstract: A ventilation insert for textiles, with at least one layer, covered at least partially by an absorption material and having ventilation openings, the openings being at least partially closeable via a liquid by swelling of the absorption material, obtainable by: a) treating a layer having ventilation openings with a mixture, containing a wetting agent, initiator, polymerizable monomer or oligomers, and a cross-linking agent, as a preliminary stage for the absorption material; and b) polymerizing the monomer or oligomer to form the absorption material while forming a bonded connection between the absorption material and the layer. The ventilation insert has a relatively low thickness, a low weight per unit area, and high flexibility permanently and independently of moisture after economical production, via one layer, self-sealingly closing ventilation openings, and containing the absorption material. The absorption material is connected to the layer by bonding, at least in some regions.

Abstract: A membrane for selective transport of substances includes: a porous substrate with a comb polymer. The comb polymer contains a polymer main chain and several lateral chains covalently bonded to the polymer main chain. At least one of the several lateral chains has at least one Lewis-acid and/or Lewis-base functionality.
