A new strategy for the selective coating of tin sulfide (SnS) on the surface of moth‐eye patterned (MEP) conducting polymer film is studied by considering the optical properties of the antireflective moth‐eye pattern and flexibility of polymer films. The semiconductor SnS is selectively coated on the surface of MEP microdomes of poly(3,4‐ethylenedioxythiophene) poly(styrene‐sulfonate) (PEDOT:PSS) film. The SnS coated MEP film is obtained by using pore selectively SnS thin layer functionalized polystyrene honeycomb‐patterned porous (HCP) film as a template. Aqueous PEDOT:PSS solution is poured on the SnS functionalized HCP films and detached for the fabrication of SnS coated MEP films. The films show a satisfactory photo‐responsive property under solar stimulated light illumination due to the antireflective MEP structure of PEDOT film and homogenous SnS coating on the surface of the conducting polymer.

“…This method is straightforward and easy operation because it is not required to remove the template, which has been considered as a prospective technique generally applied to capture protein/enzymes compared to typical methods. More interestingly, various kinds of polymer materials (such as block, [26] linear, [27] star‐like, [28] amphiphilic polymers), inorganic materials [29] and hybrid materials [30] have been extensively exploited for the fabrication of patterned porous film possessing various functions by using this method.…”

Micropattern of bioactive substances in food, such as functional protein and enzyme immobilization, play a crucial role in catalysis, proteomics, tissue engineering, nutrition transportation and biological detection. Currently, various techniques have been reported for the immobilization of bioactive substances on solid but the fabricated methods are often not facile and universal. In this study, we overcome these problems to localized capture ovalbumin (OVA) and trypsin (Try) efficiently by fabricating patterned porous film via simple breath figure approach. Upon optimization of preparation conditions, ordered honeycomb porous film were obtained. We confirmed the morphology and investigated thermostability and surface wettability of porous film. The immobilization of OVA and Try was confirmed by confocal laser scanning microscopy and SDS‐polyacrylamide gel electrophoresis, respectively. To our best knowledge, this work is the first report on patterning and trapping of food protein and enzyme via self‐organized patterned porous film. Our findings are essential for establishing a new convenient and efficient route to design food protein/enzyme‐trapped porous film materials, which opens a new sustainable way for food protein/enzyme immobilization and expected to used in the food industry, biological applications, and so on.

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.
