“…It has been found that even the superhydrophobic polymers, such as PS, can also achieve honeycomb patterns. To obtain the ideal pore size and pore distribution, some researchers modified the traditional BF process by constructing an alcohol-water mixed vapor atmosphere to replace the water vapor [22], by expanding the casting method from drop-casting to dip-casting and spincoating [23] or via thermal annealing to tune the morphology and hydrophobic properties of porous block copolymer films [24]. It was reported that humidity, viscosity and the behavior of phase separation played an important role in the formation of ordered patterns [25].…”

Honeycomb porous polystyrene (PS) films with an aspect ratio of pore depth to pore diameter at approximately 1.0 were fabricated using the breath figure (BF) method. Two modes of water droplet coalescence in the pore growth were observed in real-time by optical microscopy. Pore size significantly increases with the increase in humidity and the decrease in substrate temperature. The porous pattern could emerge even at room temperature under high humidity of 80%. Boiling point and solvent density significantly influence the pore distribution and pore depth. Chloroform and tetrahydrofuran achieve more uniform hexagonal patterns than benzene and dichloromethane. Subsequently, to obtain nanometer porous PS film, the fast-evaporation BF process was designed by regulating the gradient substrate temperature and evaporation time, and porous mesoscopic PS film was obtained. The minimum pore diameter and corresponding pore depth are about 120 nm and 27 nm, respectively. Finally, the fast-evaporation BF process was applied to the honeycomb film formation of photovoltaic polymer poly(3-hexylthiophene) (P3HT), and the heat-resistant polymers polysulfone (PSF) and polyimide (PI).

Ordered porous membranes have wide and important application prospects in the fields of filtration, separation, catalysis, biomedicine, etc., and have attracted growing interest in the field of material science. Among diverse membrane preparation approaches, breath pattern method has been widely concerned due to its simplicity in the preparation, ease in tuning the structure/property and functionality of formed membranes, and broad utility for various polymers. With the development of material design, the application spectrum of breath figure membrane has been greatly expanded. However, since the pore morphology of porous membrane is influenced by many factors, the controlling mechanism of normalization has not been clear yet. In this paper, the research progress of film-forming materials in recent years is reviewed, and the correlation between pore formation and pore morphology is discussed in details. This information will provide a systematic and in-depth perspective for research in this filed and an important guideline for the preparation of the ordered porous films with divergent applications.
