In this report titled "Photocrosslinking-induced Phase Separation in Evaporative Solvents: Formation of Skin Layers and Microspheres", we investigated the structure formation of films obtained via photocrosslinking of precursors during the evaporation of solvents. The film structure after processing is highly hierarchical, featuring a skin layer on top of a layer of microspheres formed via reaction induced phase separation mechanism. More importantly, the feature size of structures can be readily achieved by changing processing parameters including N2 flow rate, UV intensity and precursor concentrations.
