Abstract
The present disclosure provides a method for the surface modification of microstructured components having a polar surface, in particular for high-pressure applications. According to the method, a microstructured component is contacted, in particular treated, with a modification reagent, wherein the surface properties of the component are modified by chemical and/or physical interaction of the component surface and of the modification reagent.
Claims14
A discharge apparatus for fluids comprising a microstructured component comprising a surface modification obtained by contacting the surface of the microstructured component with a modification reagent, thereby modifying the properties of the surface by the chemical and/or physical interaction between the microstructured component surface and the modification reagent;
- wherein the modification reagent comprises at least one modifier, wherein the modifier is a silane of the general formula (III):
- R4-nSiXn
- wherein
- R is C10-C16 alkyl,
- X is selected from C1 alkoxy and C2 alkoxy, and
- n is 3;
- and
- wherein the at least one modifier is at a concentration of from 0.001 to 2 mol/L based on the modification reagent.
A microstructured component for use in a microfluidic system, comprising an outer surface, at least one inlet opening, at least one outlet opening, and inner surfaces formed by microstructures, wherein the inner surfaces are modified, at least in part, with a silane modifier of general formula (III):
- R4-nSiXn
- wherein
- R is C10-C16 alkyl,
- X is selected from C1 alkoxy and C2 alkoxy, and
- n is 3.
