WebJun 10, 2013 · This confirms our hypothesis that covalent cross-linking of the system inhibits the shift of the bulk mechanics to higher strains (Fig. 4A, Inset); moreover, these data suggest that, in the absence of covalent cross-links, the nonpermanent coupling of monomers is the origin of the observed change of the mechanical properties of the … WebOct 7, 2024 · The utility and lifetime of materials made from polymer networks, including hydrogels, depend on their capacity to stretch and resist tearing. In gels and elastomers, those mechanical properties are often limited by the covalent chemical structure of the polymer strands between cross-links, which is typically fixed during the material synthesis.

WebJan 25, 2024 · A newly recognized action of organophosphates (OP) is the ability to crosslink proteins through an isopeptide bond. The first step in the mechanism is covalent addition of the OP to the side chain of lysine. This activates OP-lysine for reaction with a nearby glutamic or aspartic acid to make a gamma glutamyl epsilon lysine bond. … WebNational Center for Biotechnology Information

Crosslinking is the general term for the process of forming covalent bonds or relatively short sequences of chemical bonds to join two polymer chains together. The term curing refers to the crosslinking of thermosetting resins, such as unsaturated polyester and epoxy resin, and the term vulcanization is characteristically used for rubbers.
