UV‐Triggered Cascading Degradation of Silicone Elastomer via Self‐Fluoride Amplification

open access: yesAdvanced Science, EarlyView.
UV‐triggered degradable materials offer proficient control of functional lifetime, while having issues with trigger efficiency. This work enhances the UV‐triggered degradation mechanism of silicone elastomer by introducing the UV‐initiated synergetic fluoride self‐amplification. The silicone composite shows excellent mechanical properties and on‐demand
