2-Hydroxyethylbenzene Functionalised Stainless Steel 1×1 cm Samples


SKU: N/A Category:


The RadiCoat stainless steel-2-hydroxyethylbenzene surface coating is a multilayer film on stainless steel (SS304) consisting of 2-hydroxyethylbenzene groups, electrochemically immobilized through reduction of 4-(2-hydroxyethyl)benzenediazonium tetrafluoroborate. The multiple surface hydroxyl groups makes the surface hydrophilic. In addition, these nucleophilic groups may serve reactive moieties to chemically immobilize e.g. biological markers or chemical functional groups. As an example, RadiCoat stainless steel-2-hydroxyethylbenzene can readily be used for immobilization of initiators for atom transfer radical polymerization (ATRP), and thereby as a platform to create so called polymer brushes (Langmuir 2011, 27, 1070–1078; ACS Appl. Mater. Interfaces 2014, 6, 21308−21315). RadiCoat stainless steel-2-hydroxyethylbenzene surface films are 5-7 nm and highly uniform.
