Abstract

La presente descripción se dirige a una matriz de espuma de celda cerrada para suministrar oxígeno, que contiene un material superabsorbente con oxígeno atrapado dentro del material superabsorbente. El material superabsorbente tiene al menos 15 por ciento en masa de ácido carboxílico, sulfónico o fosfórico monoetilénicamente insaturados o sus sales, un éster de acrilato o metacrilato que contiene un grupo funcional alcoxisilano, y un glicol hidrófilo copolimerizable que contiene un monómero de éster. Para producir la matriz de espuma de celda cerrada para suministrar oxígeno, se añade un catalizador de hidróxido alcalino al material superabsorbente para formar una capa de hidrogel. Después, se añade un precursor de oxígeno a la capa de hidrogel. La capa de hidrogel se calienta para producir oxígeno mediante la reacción del catalizador de hidróxido alcalino y el precursor de oxígeno lo que atrapa de esta manera al oxígeno en la matriz de espuma de celda cerrada formada.
