Abstract
Se describe un material absorbente poroso que comprende un polímero absorbente insoluble en agua, hinchable con el agua. El material absorbente comprende un poliéter y/o un polication unido al polímero absorbente, por lo que el ángulo de contacto de la sangre sobre una superficie del material absorbente es de aproximadamente 0 grados a aproximadamente 40 grados. Debido a la capacidad mejorada de humectacion con líquidos, también como la estructura porosa, el material absorbente puede proveer características absorbentes superiores con líquidos, en particular con la sangre.
