Abstract: Abstract Resilient poly(urethane urea) aerogels are synthesized from aromatic diisocyanates, aromatic diamines, aliphatic polyols, and a trifunctional amine crosslinker. Polyurethane prepolymers are synthesized with isocyanate end groups by reacting the polyol with 4,4′-diphenylmethane diisocyanate in… read more here.
