“…According to Wang's report as a reference, 45 the WLED lamps were prepared with commercial violet light chips (365 nm, 3.2 V) as the excitation source and the obtained WLE materials as coatings. First, the obtained WLE materials ( TL-Eu or TL-Eu 1 Tb 9 @PMMA ) were dispersed in an epoxy resin AB adhesive (equal mass of 1 : 1) with a weight ratio of 1 : 1.…”

Multicolor lanthanide‐doped polymers have found versatile applications in data encryption, sensing, and smart display. However, multiple components, sophisticated design, and complex preparation procedures are often required. In contrast, their intrinsic and multicolor fluorescence emission is been effectively used. Herein, Eu‐doped polyurethane (ETP@PU), integrating tunable multicolor emission, self‐healing, and multi‐responsiveness, is prepared through a facile route via step‐growth polymerization of PU using commercial Eu‐ligand (Eu(TTA)3Phen, ETP) as a fluorophore. FTIR and XPS analysis demonstrate the successful coordination of Eu3+ with carbamate groups of PU, which not only enhances the mechanical properties of PU but also bestows unique luminescent properties. With increasing ETP content, the intrinsic fluorescence of PU declines, while that of Eu displays a discernible enhancement, resulting in the tunable multicolor emission. The highest quantum yield of Eu‐related emission reaches 71.3% due to the robust coordination and efficient energy transfer between Eu3+ and PU. Moreover, the ETP@PU exhibits excellent self‐healing capacity and multi‐responsiveness, and their potential applications are also investigated in the field of light‐emitting diodes, data encryption, and self‐healing process monitoring. This work provides a facile and efficient strategy to develop multicolor lanthanide‐doped polymers promising for various applications.

Superhydrophobic microarchitectured polyolefin surfaces are currently used intensively in various industrial applications. However, the deployment of products made of these materials into practical application is typically constrained by their inferior dry sliding behaviors, which stem from their limited strength and toughness. To obtain reinforced and toughened superhydrophobic microstructured surfaces that can be easy to demold and overcome friction in the workplace, elastomeric ethylene–octene copolymer (POE) and rigid graphene (GP) were introduced into the polypropylene (PP) matrix to prepare microstructured PP/POE/GP surfaces by compression molding. The elongation at break is significantly improved by 2000% and reached up to 520.33%. The contact angle (CA) of the microstructured PP/POE/GP surface increases to 154.4°. They exhibit superhydrophobic and low adhesion characteristic, that is, lotus effect. The enhanced toughness of PP/POE/GP composites reduces wear debris and damage to microarchitecture during the abrasion process. Even after the microstructured PP/POE/GP surfaces were worn after a distance length of 3000 mm, they still exhibited superhydrophobic, but high adhesion characteristic, that is, petal effect. The controlled shape‐morphing microarchitectures formed on the microstructured PP/POE/GP surface abraded after 1000 mm, possessing wetting stability during droplet impacting.Highlights The elongation at break of composites was improved by 2000% through adding POE. The composite microstructure deforms to consume energy during abrasion and POE reinforces this energy dissipation process. POE improves fracture toughness and wetting stability of composites.
