We have developed a transparent organic polymeric material that can repeatedly mend or “re-mend” itself under mild conditions. The material is a tough solid at room temperature and below with mechanical properties equaling those of commercial epoxy resins. At temperatures above 120°C, approximately 30% (as determined by solid-state nuclear magnetic resonance spectroscopy) of “intermonomer” linkages disconnect but then reconnect upon cooling, This process is fully reversible and can be used to… 
Silica-Like Malleable Materials from Permanent Organic Networks
A polymer shows thermoset-like stability while displaying melt processability like that of a thermopolymer. Permanently cross-linked materials have outstanding mechanical properties and solvent
Photoinduced Plasticity in Cross-Linked Polymers
This work demonstrates a cross-linked polymer that, upon exposure to light, exhibits stress and/or strain relaxation without any concomitant change in material properties.
Externally triggered healing of a thermoreversible covalent network via self-limited hysteresis heating.
The fracture healing of a novel Diels–Alder crosslinked network embedded with magnetically susceptible particles that heat in the presence of an electromagnetic fi eld is demonstrated, allowing the material to be heated in situ while also exploiting the self-limiting heating behavior of ferromagnetic particles, which minimizes irreversible reactions.
Intrinsic self-healing polymers with a high E -modulus based on dynamic reversible urea bonds
One of the hardest self-healing polymers ever reported has been prepared using the reversible bonds of sterically hindered urea groups. Polymers that can re-form internal chemical links after being
Thermo-responsive mending of polymers crosslinked by thermally reversible covalent bond: Polymers from bisfuranic terminated poly(ethylene adipate) and tris-maleimide
Abstract Remending properties of a network polymer with reversible reactivity are described. The network structure is constructed by a Diels–Alder (DA) reaction between furyl-telechelic poly(ethylene
Macromolecular design of a reversibly crosslinked shape-memory material with thermo-healability
Abstract A new thermoresponsive self-healing polymer thermoset ((1.5M/F)DA-PDMS-PU) based on the Diels–Alder (DA) reaction between furan and maleimide groups was developed. The material exhibited
A thermally-stable self-mending polymer networked by Diels–Alder cycloaddition
Abstract A novel self-mending polymer with high thermal stability is developed based on the DA reaction between anthracene and maleimide. A network polymer, PEAA 2 M 3 is prepared by the DA reaction
Epoxy Resin-Inspired Reconfigurable Supramolecular Networks
With the goal to push the mechanical properties of reconfigurable supramolecular polymers toward those of thermoset resins, we prepared and investigated a new family of hydrogen-bonded polymer
Dynamically Cross-Linked Polydimethylsiloxane Networks with Ambient-Temperature Self-Healing
Dynamically cross-linked polymer networks have promising potential to serve as self-healing materials, but this is often limited to occur at elevated temperature. We overcome this limitation by
Thermo-resettable cross-linked polymers for reusable/removable adhesives
Resettable thermosetting adhesive systems have been explored with the help of a thermo-reversible Diels–Alder (DA) reaction between a furan-bearing random copolymer and bismaleimide as a dynamic bond
