外文摘要：Fabricating photonic crystals (PCs) with dynamic multi-stimuli-responsive structural colors, recordable colors, and self-healable properties is significant for their emerging applications, yet remains a big challenge. Here, an all-in-one multifunctional PC (MFPC) film with outstanding mechanochromic, thermochromic, solvatochromic, color/shape-recordable, self-healable, and adhesive functions is designed and prepared by simply non-close-assembling silica particles into the unique 2-[[(Butylamino)carbonyl]oxy]ethyl acrylate (BCOEA) followed by photopolymerization. The success is mainly due to the rational combination of non-close-packing structures and BCOEA's characteristics, including its urethane groups with numerous sacrificial hydrogen bonds, temperature-dependent refractive index, swellable and deformable polymer network, as well as low glass-transition temperature. The MFPC's hue and color saturation can be reversibly and dynamically modulated by strain/pressure/solvents and temperature, respectively, thereby realizing visually and spectrally sensing these stimuli. More interestingly, the color-responsiveness combined with other functions endows MFPCs with fascinating emerging applications, including multilayer optical filters, inkless printing, reconfigurable multicolor patterns, stretching-based anti-counterfeiting, etc. This work offers a new perspective for designing next-generation smart photonic materials and will facilitate their all-round applications. Multifunctional photonic crystals with remarkable mechanochromic, thermochromic, solvatochromic, color/shape-recordable, self-healable, and adhesive functions have been fabricated by non-close-assembling silica particles into the unique commercially available 2-[[(Butylamino)carbonyl]oxy]ethyl acrylate with abundant stimuli-responsive and chemical/physical properties. These functions result in interesting emerging applications of photonic crystals, including multilayer optical filters, inkless printing, reconfigurable multicolor patterns, stretching-based anti-counterfeiting, etc. image
