“…Meanwhile, Maruyama [ 51 ] proposed a mechanism as shown in Figure 4 . They believed that the Marangoni convection and capillary forces were the main driving forces [ 34 , 35 , 36 , 52 , 53 , 54 , 55 ]. The polyion complex was used as the building unit with chloroform as the solvent.…”

Honeycomb films with various building units, showing potential applications in biological, medical, physicochemical, photoelectric, and many other areas, could be prepared by the breath figure method. The ordered hexagonal structures formed by the breath figure process are related to the building units, solvents, substrates, temperature, humidity, air flow, and other factors. Therefore, by adjusting these factors, the honeycomb structures could be tuned properly. In this review, we summarized the development of the breath figure method of fabricating honeycomb films and the factors of adjusting honeycomb structures. The organic-inorganic hybrid was taken as the example building unit to discuss the preparation, mechanism, properties, and applications of the honeycomb films.

“…The pentablock copolymer of PTFEMA-b-PMMA-b-PEG-b-PMMA-b-PTFEMA (M n ¼ 26 790 g mol À1 , PDI ¼ 1.49) was synthesized through atom transfer radical polymerization in our previous study. 33 Water used in all experiments was deionized and ultraltrated to 18.2 MU with an ELGA Labwater system. All other reagents (chloroform, glycerol, formic acid, ethylene glycol, ethyl acetate, ethanol, isopropanol, methanol, the methyl silicone oil) were analytical grade and used without further purication.…”

“…31,32 In present work, the pentablock copolymer of PTFEMA-b-PMMA-b-PEG-b-PMMA-b-PTFEMA was chosen as lm-forming material to explore the inuence of surface thermodynamics to the surface morphologies and their hydrophobic properties. Based on our preliminary work, 33 the effect of liquid substrates with different surface tension and viscosity on the morphologies were investigated. In addition, the surface hydrophobic properties including wettability and water droplet impact behaviour of the lms with different morphologies such as at, porous and peeled lms were tested, which have not been systemically investigated previously.…”

The breath figure (BF) technique is regarded as a powerful tool for the fabrication of strictly ordered and closely packed nano-and micro-porous films. It is a facile, economical, and versatile approach in which condensed water droplets serve as a benign template by rearranging on the polymer solution surface. They direct the assembly of polymer molecules into ordered patterns. Furthermore, the morphology of the pores can be adjusted and optimized by controlling several critical experimental parameters such as the film-forming system of the materials and the circumstances. This technique has a vast range of potential and promising applications in relevant areas such as separations, templating, stimuli-responsive surfaces, biosensing and photoelectric materials. However, the possible interplay of general mechanisms for the formation of all breath figure systems is complex, because each casting system is unique. In some cases no definite conclusion on the effect of each variable could be drawn until now. We review investigations at home and abroad including our group over the last five years on the preparation of honeycomb porous films using the breath figure method. We summarize and analyze their formation, influencing factors, function technologies and the applications of these porous films, and attempt to reveal the principles behind the formation of holes and the control of pore morphology. This work is expected to lay the foundation for follow-up studies and applications.
