Abstract

Silver-containing composites were prepared via the sorption of silver ions by melamine-formaldehyde polymer (MFP) modified with diisocyanate oligomers. Introducing the modifiers into a structure of MFP improves microphase separation processes and increases the permeability of the matrix and the concentration of coordination active functional groups. Sorption capacity of modified MFP to Ag+ ions reaches 6.5 · 10−2 g/g. Ag-containing nanocomposites obtained are characterized by a heterogeneous structure, increased hydrophilicity, and gradient distribution of silver in a bulk of the polymers.
