Polymers is silicon
WebIn 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 polymers or natural polymers (such as proteins).. In polymer chemistry "cross-linking" usually refers to the use of cross-links to promote a … WebJan 28, 2024 · Several polymers were screened for their selectivity and resistance to buffered hydrofluoric acid (BHF) etching. A water-soluble cellulose-based polymer, DC01, was subsequently found to reduce the etching of Si3N4 selectively, owing to strong interactions between the polymer and underlying bulk material once the native oxide is …
