摘要

Abstract

Smart materials with a combination of tough solid-like properties

fast self-healing and optical responsiveness are of interests for the development of new soft machines and wearable electronics. In this work

tough physically cross-linked elastomers that show high mechanical strength

intriguing temperature-adaptable self-healing and fluorochromic response properties are designed using aluminum (Al) and fluorescent europium (Eu) ions as cross-linkers. The ionic Al-COOH binding is incorporated to construct the strong polymer network which mainly contributes to the mechanical robustness of the elastomer consisting of two interpenetrated networks. The Eu-iminodiacetate (IDA) coordination is mainly used to build the weaker but more dynamic network which dominate the elasticity

self-healing and luminescence of the elastomer. Moderate Eu

and Al

contents give these supramolecular elastomers high toughness. The temperature-sensitive Eu-IDA coordination enables tunable self-healing rate and efficiency along with fast Eu-centered “ON/OFF” switchable red emission. The mechanical

self-healing and luminescence properties of these elastomers can be adjusted by tuning the ratio of the two types of metal ions. This elastomer is potentially applicable for biosensors

wearable optoelectronics and anticounterfeiting materials.
