Abstract Nanoporous polymers with three-dimensionally continuous pore structure are beneficial in many applications as diffusion through the interconnected porous space is facilitated. Here we report such nanoporous polymers with tunable mechanical properties can be readily fabricated as free-standing films via photoinitiated polymerization-induced microphase separation (photoPIMS) method. In contrast to thermally initiated polymerization that requires high polymerization temperature and lengthy polymerization time, we will show that photoPIMS process allows production of crosslinked block polymer films at ambient temperature with short polymerization time, and subsequent etching of the sacrificial block from the film results in the desired nanoporous film. We will further demonstrate elastic nanoporous films can be fabricated by adjusting the composition of the polymerization mixture for the photoPIMS.
