The invention relates to a porous PEEK polymer element having a porous PEEK polymer structure and at least one trimodal pore distribution. The invention also relates to a method for producing said porous PEEK polymer element, according to which: a) a PEEK polymer is brought into contact with a composition comprising at least one organic solvent, b) the polymer and composition are heated to a temperature at which the PEEK polymer dissolves, c) at least one pore-forming agent is added, d) the mixture produced in c) is cooled to a temperature at least equal to, or lower than, the temperature at which the PEEK polymer precipitates, e) said cooled mixture is shaped to form a shaped object, f) the organic solvent and pore-forming agent are removed, and g) the PEEK polymer element is recovered. |
