WebCrosslinking 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. [2] WebApr 10, 2024 · Therefore, chemical cross-linking or mixing of chitosan with natural polymers such as gelatin is a method to improve its mechanical properties. The physical, chemical and mechanical properties of hydrogels can be enhanced by being modified with other polymers and/or cross-linking agents.
WebJul 1, 2024 · EDC is a frequently used protein crosslinking agent applied in medicine that can activate carboxyl groups of amino acids such as aspartic acid and glutamic acid to facilitate the formation of ester bonds between the carboxyl groups of gelatin and the hydroxyl groups of PVA [29]. WebApr 1, 2001 · GTA crosslinking affects dramatically the stiffness of gelatin films, as previously reported [9].Typical stress–strain curves recorded from samples crosslinked with GTA solutions at different concentrations are reported in Fig. 1.It is evident that the extensibility of the films decreases, whereas the stress at break increases, on increasing …
WebDec 15, 2010 · After the crosslinking process, the chitosan/gelatin substrates crosslinked by TPP were immersed in the simulated body fluid (SBF) for 14 days at 4 °C. For comparison, GA was used instead of TPP as a crosslinking agent, which forms colavent bonds, and all other steps were the same.
