The present invention relates to a composite material for filling a wound, which includes a shell containing a material or a group of materials forming fluid flow channels, said shell consisting of a self-supporting interface material formed by a thin film of a composition including a hydrophobic matrix and comprising through-holes, said hydrophobic matrix including, for 100 parts by weight of a three-block styrene-saturated olefin-styrene copolymer having a viscosity of 0.2 to 2 Pa.s, as measured in a solution of 10 % (by weight) in toluene, 400 to 1,220 parts by weight of a plasticiser, preferably a plasticising oil, and 0 to 720 parts by weight of Vaseline, with the additional specification that the total amount of plasticiser and Vaseline is no lower than 750 parts by weight and the amount of Vaseline is 400 to 720 parts by weight when the amount of plasticiser is 1,000 to 1,220 parts by weight. |
