摘要：
1. Polydioxanone film containing essentially cylindrical polydioxanone columns at least on one side； these columns have diameters of about 0.2 to 3 microns and a height of about 2 to 20 microns from the surface of the film. 2. The polydioxanone film according to claim 1, wherein the columns are treated with oxygen plasma to increase the oxygen content in said polydioxanone columns compared to untreated polydioxanone columns. The polydioxanone film according to claim 1, wherein the cylindrical polydioxanone columns have diameters of about 0.6 to 1 μm and a height of about 20 μm from the surface of the film and have superhydrophilicity, having a static contact angle with water of less than 10 °. 4. The polydioxanone film according to claim 2, wherein the cylindrical polydioxanone columns have a height of about 20 μm from the surface of the film and are superhydrophilic, having a static contact angle with water of less than 10 °. 5. The polydioxanone film according to claim 1, which has a protein adsorption capacity of from about 2.5 to 6.0 μg / cm of the film surface. The polydioxanone film according to claim 5, which has a protein adsorption capacity of from about 4.0 to 6.0 μg / cm of the film surface. A method of adsorbing proteins, comprising passing a protein solution through a polydioxanone film containing substantially cylindrical polydioxanone columns on at least one side； these columns have diameters of about 0.2 to 3 μm and a height of about 2 to 20 μm from the surface of the film. The method according to claim 7, in which the columns are treated with oxygen plasma to increase the oxygen content in these polydioxane columns compared to not1. Полидиоксаноновая пленка, содержащая по существу цилиндрические полидиоксаноновые столбики по меньшей мере на одной из сторон； указанные столбики имеют диаметры примерно от 0,2 до 3 мкм и высоту примерно от 2 до 20 мкм от поверхности пленки.2. Полидиоксаноновая пленка по п. 1, в которой столбики обрабатываются кислородно
