The present invention is directed towards a method for the preparation of macroporous or mesoporous polymer films in hollow fiber geometry. The method according to the present invention reliably produces macroporous or mesoporous homopolymer or copolymer films in hollow fiber geometry having an ordered porous structure. Preferably, the pores are isoporous. The method involves the purging or casting a polyol adjacent to a film forming polymer solution of at least one homopolymer or at least one copolymer in a suitable solvent while polyol diffuses in and then condenses out of the film forming solution before the solution is immersed into a coagulation bath. The methods also require the presence of a carrier solution or carrier substrate during spinning or casting. The method makes macroporous or mesoporous film formation possible with a single step processing method.
