PROCESS FOR THE FUNCTIONALIZATION OF A SURFACE

摘要

It was the object to perform surface functionalization with as low as possible a procedural effort and without deleterious side effects, wherein the functionalized surface is to have a permanent chemical activity and a high degree of substitution (DS) of higher than 1.;According to the invention, the functionalization is performed with a dissolved oligo- or polysaccharide derivative which contains at least one free functional group, especially an amino group, linked through a polar carbamate linkage and a spacer (X), according to the general formula I:;

1. A process for the functionalization of a surface, which consists of or comprises synthetic polymers and natural polymers, such as polysaccharides and proteins, paper, glass, ceramic, silicon, metals and metal oxides, and is contacted, for surface functionalization, with a solution containing at least one compound for forming a material composite with the surface material, characterized in that as said at least one compound for forming the material composite, a dissolved oligo- or polysaccharide derivative is employed which has at least one free functional group R1 linked through a polar carbamate linkage and a spacer (X), according to the general formula I: with R1=NH2, SH or OH; R2 or (independently) R3=H orand
