“…Furthermore, they fabricated microporous films of urushiol-formaldehyde diethylenetriamine polymer (UFDP) with different morphologies via the breath figures approach. [40] It is found that the drying time strongly affects the morphology of the UFDP microporous films. That is, more homogenous pore size distributions can be observed in a short drying time, whereas the disordered porous films will be obtained with prolonged drying times.…”

“…For example, via water‐assisted assembly process, urushiol–formaldehyde polymer (UFP) films were successfully prepared on solid substrates by Xu et al., [39] and the results suggest that the as‐prepared UFP films had hydrophobic property and good acid‐alkali resistance. Furthermore, they fabricated microporous films of urushiol–formaldehyde diethylenetriamine polymer (UFDP) with different morphologies via the breath figures approach [40] . It is found that the drying time strongly affects the morphology of the UFDP microporous films.…”

Raw lacquer is a kind of natural polymer coating with excellent performance. The lacquer film formed after drying of pure natural raw lacquer has the advantages of hard quality, heat resistance and corrosion resistance. However, natural raw lacquer also has some disadvantages. For example, it must be dried at a specific temperature and humidity to form a film, difficult to spray, dark color, poor alkali resistance, easy to cause human skin allergy and so on. Due to urushiol is the main film‐forming material in raw lacquer, its performance and drying film‐forming process will directly affect the properties of the lacquer film. Taking advantage of the particularity of its structure, urushiol can be modified in its drying film‐forming process, so as to speed up its drying film‐forming process or obtain a modified lacquer film with excellent performance. Thus, the research on raw lacquer and its modification mainly focuses on the modification of urushiol, the main film‐forming substance of the raw lacquer. This paper reviews the modification and combined methods of the natural urushiol by researchers in recent years, mainly including urushiol polymerization catalyzed by proton acid, urushiol polymerization initiated by UV irradiation, copolymerized with other polymer materials, reacted with metal compounds to form urushiol metal polymers, and formed composite coatings with multi‐wall carbon nanotubes, graphene oxide, nano‐TiO2 and so on. The modified lacquer has shown excellent performance in some aspects, such as the gloss and hardness of the lacquer film have been significantly improved, the heat resistance, acid and alkali resistance have been enhanced, the ageing resistance and solvent resistance have been improved, the impact strength and toughness have been enhanced, the curing time of the lacquer film has been greatly shortened and so on. Then the application fields and development trends of the modified raw lacquer are discussed, hoping to provide a theoretical basis for the further development and utilization of raw lacquer.

“…The pore size of honeycomb films is equal to the size of the water droplets; thus, controlling the size of the water droplets is important. Various parameters control the pore size of water droplets, including evaporation time [53], interfacial tension between water and solution, and solvent boiling point, which affects evaporation time [54,55]. When the boiling point of the solvent is high, the solvent evaporates slowly, and evaporative cooling is not sufficient to condense water droplets from the atmosphere; there must be a temperature difference between the solution surface and the dew point of the atmosphere for condensation occur.…”

The breath figure method, which is used to form porous films from water droplet templates, has attracted considerable interest because it is simple and applicable to a wide variety of materials. Research on breath figures took off after the 2000s, accompanied by new polymer synthesis methods, fabrication methods, and a wide variety of applications. There are several comprehensive reviews of the applications of the porous films, which are usually called 'honeycomb films' because their hexagonally packed porous structure resembles honeycombs. However, new materials, progress in preparation technologies for controlling nanoand microstructures, and large-area fabrication are still areas that require further research. Furthermore, new applications of honeycomb films have emerged. In this review, the recent development of honeycomb films prepared by the breath figure techniques and their numerous applications are summarized. The production of honeycomb films can be performed on an industrial scale, greatly broadening their possible applications in areas such as optics, photonics, surface science, biotechnology, and regenerative medicine. Present problems and future perspectives are also discussed.
