Abstract

A method of producing a polymer part comprising the following steps: (a) incorporating a hydrophobic small molecule into the polymer before, during or after manufacture of the polymer part, the hydrophobic small molecule and the polymer being essentially inert to one another; and (b) annealing the polymer part to induce migration of the hydrophobic small molecules to a surface of the polymer part to provide that surface with a specified degree of hydrophobicity defined by the combination of the polymer and the hydrophobic small molecule; is described. Polymer parts made according to the method are also described.
