The effects upon the composite film behavior in response to the solvent concentration, type of solvent and relative humidity were studied. Films containing homogeneously dispersed micrometre-sized pores were obtained. The optical and morphological behavior were investigated using optical microscopy and scanning electron microscopy. The films obtained have various potential applications as surface coating materials with color changing properties, such as whiteboards, device displays or advertising surfaces.Material chemistryphoto-optical switching componentsmorphological analysispolymer porous filmsporous organic polymersPreparation of functional coating films using breath figure (BF) method and the study of morphological, optical and wettability behavior with varying experimental conditionsArtÃculohttps://doi.org/10.1080/1023666X.2023.2175167
