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) . WebBond exchange in polymer networks has received much attention as a route to recycling and circularity of materials which are typically not reprocessable. In addition, the presence of dynamics bonds can lead to large impacts on the transport of guest molecules relevant for membrane separations, ion conducting electrolytes, and thermal transport.
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 … WebDynamic photopolymer networks that take advantage of the thermodynamically controlled reversibility of thiol–succinic anhydride adducts were synthesized from commercial substrates and investigated …
