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.

Abstract: Highly transparent polyisocyanurate–polyurethane (PUR–PIR) aerogels were synthesized, and their optical properties were studied in detail. After determining the density and structural parameters of the manufactured materials, we analyzed their optical transmittance. It was demonstrated that… read more here.
