Fabricating a single polymer network with combination of multi-shape memory effect (multiple-SME), solid-state plasticity, recyclability and self-healing behavior remains challenge. We designed imine bond ionic hydrogen dual cross-linked polybutadiene (PB) networks. The resulting PB networks showed triple-shape effect, where bonds could be used to fix the permanent shape glass transition acted as segments for fixing/releasing temporary shapes. Additionally, dynamic offered outstanding behavior. This strategy provides some insights preparing polymers integrating multiple-SME multi-functionality.
