摘　　要：Recently,waterproof lighting and luminescent displays have been achieved in perovskite–polymer composite materials.However,practical large-area display applications are still limited to the strong electrostatic adhesion(EA)and high productivity.To overcome these deficiencies,large-area(~600 cm2)homogeneous perovskite–polymer fiber membranes(PPFMs)are synthesized by an electrospinning strategy in this work.Due to the microscopic cladding of the hydrophobic polymer fibers,the electrospun PPFMs exhibit ultrastable underwater luminescence for more than 90 days,and strong EA to diverse materials without pretreatments or additional adhesives.Moreover,by utilizing a proposed programmable laser lithography strategy,designed PPFM patterns are fabricated as the assembly blocks of large-area colorful or tridimensional displays.Interestingly,due to laser thermal ablation effects,the disengaged edges of these blocks are self-stitched with high mechanical stability and operability.This work provides a simple and effective strategy to realize waterproof,self-adhesive,and large-area display applications of perovskite nanomaterials in real world settings.
