Abstract

a presente divulgação é direcionada a uma matriz de espuma de célula fechada para fornecer oxigênio contendo oxigênio de material superabsorvente preso dentro do material superabsorvente. o material superabsorvente tem pelo menos 15 por cento em massa de ácido carboxílico, sulfônico, ou fosfórico monoestetilenicamente insaturado, um éster de acrilato ou metacrilato que contém uma funcionalidade de alcoxissilano e um glicol hidrofílico copolimerizável contendo monômero de éster. para produzir a matriz de espuma de célula fechada para fornecer oxigênio, adiciona-se um catalisador de hidróxido alcalino ao material superabsorvente para formar uma camada de hidrogel. em seguida, um precursor de oxigênio é adicionado à camada de hidrogel. a camada de hidrogel é aquecida para produzir oxigênio, fazendo reagir o catalisador de hidróxido alcalino e o precursor de oxigênio, aprisionando assim o oxigênio na matriz de espuma de célula fechada formada.
