Abstract
An autonomic self-indicating material is provided, the material comprising a polymer composition or a composite material embedded with a microcapsule or a vascular structure comprising an aggregation-induced emission (AIE) luminogen. Upon mechanical damage to the material, the luminogen is released and aggregates, leading to fluorescence.
