A method for producing a porous polymer structure involves (i) forming a polymer; (ii) subsequently contacting the polymer with a nonsolvent and inducing the formation of an emulsion in which the nonsolvent is present as the dispersed phase and the polymer as the continuous phase; and (iii) removing at least some of the nonsolvent so as to leave pores within the polymer, wherein the polymer is formed by exciting one or more molecules in an exciting medium, in particular by pulsed plasma deposition. Emulsion formation in step (ii) may be induced by or in the presence of an emulsion stabilising agent. Also provided is a porous polymer structure produced using the method, and a polymer which is impregnated with an emulsion stabilising agent, for use in the emulsion formation step of the method.
