Honeycomb‐structured porous films have important applications in numerous fields, such as optoelectronic devices, tissue engineering, and micro reactors. The breathe figure method (BFM) has received much attention as a highly efficient, low cost technique to prepare honeycomb films. Pengfei Zhang, Huawei Chen, and Deyuan Zhang describe an improved BFM to fabricate well‐defined porous films by spraying atomized micro water droplets. Pore size and distribution can be well controlled by tuning process variables including spraying time, spraying flux, and solution concentration. Multi‐level honeycomb film formation is made possible by spraying atomized water droplets twice. The cover shows a SEM image of polymer films with uniform pores formed by this method.
