Claim:
1. A nanoporous material comprising a polyurethane-acrylate polymer formed by the polymerization of a urethane-acrylate star monomer of the formula (I): in the presence of a polymerization catalyst at 60° C. for 2-4 h, to give a wet gel, followed by aging of the wet gel for 24 h at 60° C., washing five times with acetone for 8 h per wash, and drying with supercritical fluid CO wherein the nitrogen atoms of the urethane moieties in the urethane-acrylate star monomer of the formula (I) are independently attached to their respective aryl rings at the 2, 3, or 4-positions of the aryl rings; wherein each of W, X, and Y independently represents a C wherein each of R1-R9 is independently a hydrogen, a C wherein the material is an aerogel.
