4D‐Printed Spin Crossover Metamaterials with Giant Programmable Positive or Negative Thermal Expansion

open access: yesAdvanced Materials, EarlyView.
Spin crossover composite filaments are implemented for the rational design of 4D‐printed mechanical metamaterials. The obtained bi‐material structures guided by a theoretical analysis based on analytical calculations and Finite Element Analysis simulations exhibit giant programmable positive or negative deformation with coefficients of thermal ...

Tough and Rapidly Relaxing Hydrogels Via Programmable Crosslink Kinetics

open access: yesAdvanced Materials, EarlyView.
A kinetic programming strategy encodes supramolecular crosslink lifetimes in single polymer networks via stoichiometric control of fast and slow hostguest interactions. This enables predictable stress relaxation on biologically relevant timescales (0.1‐100 s) while maintaining exceptional toughness (up to 14,500 J m−2), resolving the long‐standing ...
