Micrometer-sized water droplets have emerged as a promising platform to perform spontaneous redox reactions. Nevertheless, explorations concerning the utilization of microdroplet chemistry for material fabrication are rather limited. In current study, classic breath figure process was utilized conduct microdroplet-induced reduction and oxidation reaction achieve functionalization porous film. The conversions AgNO3 Ag, resazurin resorufin, 4-chloro-2-hydroxybenzaldehyde 4-chlorocatechol were successfully fulfilled by simply introducing reactant into (BF) via either atmospheric spraying or direct addition casting solution. Both reactions proven take place, induced formation condensed droplets. yield product can be dynamically manipulated tuning different experimental conditions, reaching maximum Ag content 547 mg/kg. obtained polymeric film decorated with nanoparticles used effectively catalytic substrate degradation methylene blue (MB), resulting in decrease absorption peak MB from 2.355 0.294.
