Abstract

Materiales de espuma absorbentes que con capaces de adquirir y distribuir fluidos acuosos, especialmente fluidos desechados por el cuerpo, tales como una orina. Estas espumas absorbentes combinan presiones de absorcion capilar relativamente alta y propiedades de capacidad por peso que les permiten adquirir fluidos, con o sin la ayuda de gravedad. Estas espumas absorbentes también entregan este fluido eficientemente a materiales de almacenamiento de presion de absorcion superior, incluyendo componentes de almacenamiento de fluido absorbentes a base de espuma, sin aplastarse. Estas espumas absorbentes se hacen polimerizando emulsiones de fase interna alta (HIPEs).
