Preparing non-covalent particulate compounds, comprises preparing a solution A of a modified dendrite polymer in a medium with a boiling point 1, treating the solution A with a metal precursor compound in the form of a metal salt, mixing the solution A and a solution B of reducing agent having a boiling point 2 to reduce a metal ion under and then stirring, and heating the homogenized mixture of solutions A and B in a microwave oven until the medium is vaporized and complete reduction is carried out and then cooling using nitrogen or an inert gas to produce the dispersion product. Preparing non-covalent particulate compounds, comprises preparing a solution A of a modified dendrite polymer in a medium with a boiling point 1, treating the solution A with a metal precursor compound in the form of a metal salt, mixing the solution A and a solution of reducing agent having a boiling point 2 higher than the boiling point 1 in the medium in a molar ratio of 10:1-1:1 to reduce a metal ion under conditions and then stirring at room temperature, and heating the homogenized mixture of solutions A and B under flushing with inert gas in a microwave oven while simultaneously stirring to the boiling point 1 until the medium is vaporized and complete reduction is carried out and then cooling using nitrogen or an inert gas to produce the dispersion product from the dendrite polymer material and the embedded metal nanoparticles. An independent claim is included for non-covalent particulate compounds in the form of metal nanoparticles dispersions prepared by the process comprising a composition of an amphiphilic dendrite polymer material and inter-and intra-molecular embedded metal nanoparticles in a bimodal size distribution, which are not water soluble and amphiphilic. |
