A porous absorbent material that comprises a water-insoluble, absorbent polymer. The absorbent material comprises a polyether and or a polycation bonded to the absorbent polymer whereby the contact angle of blood on a surface of the absorbent material attains from about 0 degree to about 40 degrees. Because of the improved wettability with liquids as well as the porous structure, the absorbent material can provide higher absorbent characteristics with liquids, in particular with blood.
L'invention se rapporte à un matériau absorbant poreux qui comprend un polymère absorbant insoluble dans l'eau, gonflable dans l'eau. Le matériau absorbant comprend un polyéther et/ou un polycathion lié au polymère absorbant, l'angle de contact du sang sur une surface du matériau absorbant atteignant entre environ 0~ et environ 40~. Du fait de la mouillabilité améliorée des liquides et de la structure poreuse, le matériau absorbant peut présenter des caractéristiques absorbantes supérieures pour des liquides, et en particulier pour le sang.
