Abstract
Provided is a method for forming solid substrates having high density of primary amine group on its surface, in which the primary amine groups on the surface of an aminosilylated substrate are treated with aziridine or an aziridine derivative. The surface density of the primary amine functional groups (—NH2) on the very top surface of a substrate can be drastically increased.
Claims19
A method for forming solid substrates having a high density of primary amine groups, comprising:
- introducing aminosilane groups onto a surface of a substrate to form an aminosilylated substrate having primary amine groups on the surface;
- and
- contacting the surface of the aminosilylated substrate with a solution comprising aziridine or an aziridine derivative in the presence of an acid catalyst and a solvent thereby increasing the density of primary amine groups on the surface of the substrate.
A solid substrate having high density of primary amine groups which comprises an aminosilylated substrate having a surface polymerized with aziridine or an aziridine derivative, wherein the surface of the substrate has a density of primary amine groups greater than 3.5 amines/nm2.
