Additive Manufacturing of Molecular Architecture Encoded Stretchable Polyethylene Glycol Hydrogels and Elastomers (Adv. Mater. 15/2026)

3D Printing of Foldable Bottlebrush Networks Bottlebrush molecular architecture prevents the crystallization of high molecular weight polyethylene glycol (PEG) polymers, enabling highly stretchable photocurable PEG hydrogels and elastomers for high-performance conductive solvent-free electrolytes at room temperature and for additive manufacturing of complex architectures and multi-material structures with seamless interface integration.
