Sponge-like polymeric adsorption material

Abstract

A sponge-like polymeric adsorption material prepare by a process including: preparing a linear polymer yarn from a linear polymer via melt-blow spinning, treating the linear polymer yarn with a crosslinking agent and a porogen agent; heating the treated linear polymer yarn at 130 to 150° C. for 25 to 35 seconds to obtain a fibrous polymeric adsorption material; and weaving the fibrous polymeric adsorption material to obtain the sponge-like polymeric adsorption material. The linear polymer has a molecular weight of 15,000 to 20,000 g/mol. The fibrous polymeric adsorption material includes fibers with a diameter of 4 to 6 microns. The crosslinking agent is in an amount of 1 to 3 weight % of the linear polymer. The crosslinking agent is a diacrylate ester compound having Formula J1, J2 or J3. The porogen agent is in an amount of about 1 weight % of the linear polymer. The sponge-like polymeric adsorption material has a thickness of 15-20 mm and a density of 600-720 g/L. The linear polymer has a molecular weight of 15,000 to 20,000 g/mol.
