A new fabrication process for the pore‐selective functionalization of honeycomb‐patterned porous (HCP) films is demonstrated by a modified breath figure method accompanied by an in situ chemical reaction. A polymer solution containing one reactant is cast under humid conditions containing counter reactant to facilitate a chemical reaction at condensed droplet/polymer solution interface, which results in the pore‐selective functionalization of HCP films. Polystyrene (PS) solution containing tin(II) chloride is cast under humid conditions containing aqueous hydrogen sulfide for the formation of tin sulfide (SnS)‐functionalized PS HCP films. H₂S humidity is generated by pumping ambient air through the aqueous sodium sulfide solution. Scanning electron microscopy, transmission electron microscopy, and elemental mapping analyses indicate the formation of SnS as thin layers selectively in the pores of PS HCP films.

伴随化学反应的呼吸图过程在蜂窝图案薄膜中的孔选择性SnS功能化

改进的呼吸图方法与原位化学反应一起证明了蜂窝状多孔（HCP）膜的孔选择性功能化的新制造工艺。在潮湿条件下浇铸含有一种反应物的聚合物溶液，并在其中加入反作用剂，以促进在冷凝的液滴/聚合物溶液界面处发生化学反应，从而导致HCP膜的孔选择性功能化。在潮湿条件下，将含有氯化锡（II）的聚苯乙烯（PS）溶液浇铸在含有硫化氢水溶液的条件下，以形成硫化锡（SnS）功能化的PS HCP膜。高₂通过将环境空气泵送通过硫化钠水溶液来产生湿度。扫描电子显微镜，透射电子显微镜和元素图谱分析表明，在PS HCP膜的孔中选择性地形成了SnS薄层。
