A mussel-inspired high bio-content thermosetting polyimine polymer with excellent adhesion, flame retardancy, room-temperature self-healing and diverse recyclability

“…This result proved that the adhesive had perfect environmental stability. Compared with the adhesive strength reported in the literature, 3,16,19,21,22,[34][35][36][37][38][39][40][41][42][43][44] our polymer exhibited the best performance on all substrates (Fig. 2h).…”

Carbon nanotube reinforced self-healable polythiourethane with excellent bonding strength and improved thermal conductivity

“…5(b) shows that a 0.3 wt% doping content with a lap shear strength of 12.2 MPa is the strongest hot melt composite materials in lapping stainless steel among reported those constructed by dynamic bonds to the best of our knowledge. 27,[36][37][38][39][40][41][42] As shown in Table 1, the elastic moduli of these samples first increase and then decrease with the increasing content, which are 11.6 MPa, 78.3 MPa, 130.5 MPa, 147.3 MPa, 145.8 MPa and 137.7 MPa, respectively. As shown in Fig.…”

Effect of Counterions on the Physicomechanical Properties of Copper–Nitrogen-Coordinated Metallosupramolecular Elastomers

“…Supramolecular elastomers combine the properties of both elastomers and noncovalent interactions. Owing to the reversible dynamics of noncovalent interactions, supramolecular elastomers can respond to external stimuli, leading to smart behaviors such as self-healing, − shape memory, − reversible adhesion, − and photothermal- or humidity-responsive functions. − Notably, metallosupramolecular elastomers based on metal–ligand coordination interactions possess a broad range of material properties through the choice of different ligands, metal ions, and counterions. − In particular, detailed studies in solutions have revealed that the choice of ligands and metal salts significantly affects the kinetic and thermodynamic binding properties of coordination complexes. ,− However, in metallosupramolecular elastomers, the metal–ligand coordination chemistry is applied in the solid state, , and the binding constants of metal–ligand complexes measured in solutions cannot give accurate theoretical guidance, and meanwhile, the supramolecular interactions in solutions may be counteracted by secondary effects in the solid state . Therefore, the factors influencing the properties of metallosupramolecular elastomers have their unique complexity.…”
