Polymers with microstructure patterns are crucial to many applications, such as separation, optics, electronics, metamaterials, etc. However, introducing diverse morphologies and feature sizes ranging from nanometers micrometers into large-area polymers remains a significant challenge. Here, we design material system that enables digital programming microphase separation in polymer network generate patterns. The is engineered allow of local modulus, which arrests the length scale various microstructures. These modulus-regulated microstructures exhibit either bicontinuous or sea–island morphology have ∼100 nm several micrometers. Using household devices an ink printer ultraviolet light lamp, can be programmed fine resolutions (∼100 μm) over large areas (≫100 mm). locally varied different capabilities scatter result visible pattern. We further demonstrate this soft anticounterfeiting device. This approach networks applicable provides platform for designing other functional devices.
