A 4D Printable Shape Memory Vitrimer with Repairability and Recyclability through Network Architecture Tailoring from Commercial Poly(ε‐caprolactone) (Adv. Sci. 24/2021)

4D Printable Mutifunctional Vitrimers In article number 2103682, Sungmin Park, Yong Seok Kim, Dong-Gyun Kim, and co-workers develop a 4D printable vitrimer that is translated from a commercial poly-ε-caprolactone (PCL) resin. The developed material exhibits combined characteristics of vitrimers and semi-crystalline PCL, allowing for self-repairing, welding, recycling, as well as thermadapt shape memory effects. Furthermore, active dynamic network rearrangement capabilities of vitrimers permits applying various types of fused-deposition-modeling-based printing methods.
