Abstract
A method of attaching dialdehyde starch to surfaces is disclosed. A substrate to which substances may be coupled, which substrate comprises at least one surface coated with dialdehyde starch, and products produced utilizing the substrate are also provided.
Claims11
A method of attaching dialdehyde starch to a polymer surface which does not contain chemical groups which will chemically react with dialdehyde starch, the method comprising:
- placing an aqueous solution of dialdehyde starch on the surface for a period of time sufficient for at least a portion of the dialdehyde starch to be adsorbed by the surface;
- removing the solution;
- and
- drying the surface at a temperature of from about 50.degree. C. to about 150.degree. C.
A substrate to which substances may be coupled, the substrate comprising at least one polymer surface onto which molecules of dialdehyde starch are adsorbed, the surface not containing chemical groups which will chemically react with dialdehyde starch.
