Recently, self-healing polymers and vitrimers have attracted considerable interest from investigators. Inspired by the fact that biological tissues can heal injury, preparing these synthetic materials with self-healing properties in order to maintain the mechanical strength and structural integrity of materials against injury and damage is of interest. Vitrimers are a class of crosslinked polymer networks that contain dynamic chemical bonds. Their reprocessing can be achieved via the exchange of dynamic bonds. At service temperature, vitrimers behave as conventional thermosets. Nonetheless, the exchanges of dynamic bonds can be triggered at elevated temperatures. As a consequence, the thermosets display weldability, thermoplasticity or malleability. According to the exchange mechanism of dynamic bonds, covalent adaptable networks (CANs) of vitrimers can be divided into: i) dissociative and ii) associative types. Intrinsic self-healing of polymers and reprocessing of vitrimers can be achieved via the introduction of reversible and dynamic covalent or non-covalent bonds. Dynamic covalent bonds include transesterification, disulfide metathesis, trithiocarbonate exchange, transcarbamoylation, transamination of vinylogous amides or urethanes, imine exchange, hindered urea bonds, etc. Dynamic non-covalent bonds, such as hydrogen bonds, metal–ligand coordination and π–π stacking, are also employed to achieve self-healing of polymers or reprocessing of vitrimers.
This Special Issue is concerned with synthesis, characterization, structure and properties of self-healing polymers and vitrimers. Topics of interest include, but are not limited to, the following:
- Synthesis of new self-healing polymers;
- Design of new vitrimers;
- New dynamic chemistries for self-healing of polymers and reprocessing of vitrimers;
- Characterization of self-healing behavior;
- Multiphase design of self-healing polymers;
- Property improvent of vitrimers;
- Applications of self-healing polymers and vitrimers.
Hopefully, contributions focus on synthesis, mechanisms, physical and functional properties, and/or applications of the materials. These research articles can help to compile this Special Issue to reflect the current state-of-the-art advances in this area. Both original contributions and reviews are welcome.
