通过呼吸图技术可以制备多种微孔聚合物膜。在这里，我们报告其用于形成微孔氧化锌薄膜。将乙酰丙酮锌（氧化锌前体）溶解在聚合物溶液中，在高湿度下浇铸以形成微孔膜，或者将其真空蒸发到预先形成的微孔聚合物膜上。退火导致有机材料的热解和氧化锌膜的形成，与非结构化膜相比，其显示出增加的光催化活性。
A large variety of microporous polymer films can be prepared by the breath figure technique. Here, we report on its use for the formation of microporous zinc oxide films. Zinc acetylacetonate, a zinc oxide precursor, is either dissolved in a polymer solution that is cast at high humidity to form microporous films or is vacuum evaporated onto a preformed microporous polymer film. Annealing leads to the pyrolysis of the organic material and the formation of zinc oxide films, which show increased photocatalytic activity as compared to unstructured films.
