Polymer surface with graft chains
WebNov 11, 2024 · The method of “grafting to” refers to covalently grafting a polymeric chain via its reactive functional groups onto a device surface material through chemical reactions. “Grafting from” is the method in which the target monomers were polymerized through the initiative groups that were generated beforehand on the surface substrate. http://www.socolar.com/Article/Index?aid=100084563841&jid=100000000579
