“…Polymer foams with micro‐ and nano‐sized pores have gained significant attention in the recent past as they find numerous applications such as in filtration, energy absorption, thermal insulation, catalysis, and tissue engineering scaffolds. [ 1–7 ] The current techniques to fabricate polymer foams include particulate leaching, [ 8,9 ] thermal induced phase transition, [ 10,11 ] gas foaming, [ 12 ] block co‐polymers, [ 13 ] immiscible polymer blending, [ 14 ] and solid‐state foaming. [ 15,16 ] However, majority of these techniques result in thin films with low porosity and do not offer control over the resulting pore morphology.…”
