Dynamic bond exchange
Webdynamic bond exchange, locked-in samples cooled to ambient conditions appear opaque (Figure 2a). This opacity arises from light scattering at the interfaces of nonaligned liquid crystalline domains. To further explore the impact of dynamic bond exchange on LCE network reconfiguration, we characterized the WebWe also use dynamic bond exchange as a mechanism to control mass, ion, and thermal transport in mecanically robust networks. Molecules and ions can be hindered by dense networks, while bond exchange can relax some of the constraints imparted by the mesh. Thermal transport is enhanced in dynamic networks because of the way dynamic …

WebNetworks that contain boronic ester crosslinks undergo dynamic bond exchange that enables self-healing behavior and reprocessing. However, networks crosslinked exclusively by rapidly exchanging bonds are also susceptible to creep and stress relaxation, which limits many potential materials applications. WebDynamic covalent bonds that are capable of exchanging bond connectivity between multiple molecules offer opportunities to synergize strong covalent bond energy and dynamic bond exchange (similar to noncovalent bonds, such as hydrogen bonds) .
