WebOct 21, 2024 · This discussion will provide good insight into the structural design of CBCBs for silicon-based electrodes. Keywords: construction methods; cross-linked polymer binders via chemical bonds; cross-linking chemistries; polymer binder; silicon-based electrodes; structure−performance relationships. Cross-links can be formed by chemical reactions that are initiated by heat, pressure, change in pH, or irradiation. For example, mixing of an unpolymerized or partially polymerized resin with specific chemicals called crosslinking reagents results in a chemical reaction that forms cross-links. See more In chemistry and biology a cross-link is a bond or a short sequence of bonds that links one polymer chain to another. These links may take the form of covalent bonds or ionic bonds and the polymers can be either synthetic … See more Proteins naturally present in the body can contain crosslinks generated by enzyme-catalyzed or spontaneous reactions. Such crosslinks are important in generating mechanically stable … See more Crosslinking is often measured by swelling tests. The crosslinked sample is placed into a good solvent at a specific temperature, and either the change in mass or the change in volume is measured. The more crosslinking, the less swelling is … See more • Application note on how to measure degree of crosslinking in plastics See more Crosslinking is the general term for the process of forming covalent bonds or relatively short sequences of chemical bonds to join two … See more Wide usage of the term cross-linking is also described as vulcanization in material science and engineering, mainly addressing the fast reaction between monomers and polymers and branches of rubber.
