Polymer-protected silver and gold nanoparticles are used to process various grades of paper. Using the methods of scanning electron and probe microscopy, the structure and morphology of papers were studied. When studying the samples, it was found that the immobilization of silver and gold nanoparticles on the surface of the paper depends on its structure and morphology. The results of the study show that the thickness of the surface layer of paper after processing is much larger compared to the original, and its profile is significantly complicated by the appearance of depressions and protrusions. The possibility of using colloidal solutions of silver and gold to give the papers an additional degree of protection is shown. The article presents the results of studies and their discussion.
