Abstract:
1. A method for preparing resin compositions containing uniformly dispersed nano silver particles having uniform sizes and high dispersibility, comprising: directly dissolving a silver complex prepared by reacting a silver compound represented by the formula 1 below with one or a mixture of two or more selected from the group consisting of ammonium carbamate-based compound, ammonium carbonate-based compound and ammonium bicarbonate-based compound represented by the formula 2 to 4, in a vinyl monomer in the absence of a polar solvent and a dispersing agent; radically polymerizing the vinyl monomer in the presence of a radical polymerization initiator; carrying out decomposition of the silver complex and reduction of silver ion to form nano silver particles during the radical polymerization; and removing volatile decomposed product by heating the obtained resin after completion of the radical polymerization, wherein the radical polymerization initiator is selected from the group consisting of α,α′-azobisisobutyronitrile (AIBN), dibenzoylperoxide, tertiarybutylperoxybenzoate, ditertiarybutylperoxide, tertiarybutylperoxy 2-ethylhexanoate, tertiarybutylperoxyacetate, cumylhydroperoxide, dicumylperoxide and tertiarybutylhydroperoxide, wherein the vinyl monomer is one or a mixture of two or more selected from the group consisting of alkyl group-containing vinyl monomer, hydroxyl group-containing vinyl monomer, N-substituted amide-based vinyl monomer, alkoxyalkylacrylate-based vinyl monomer, cyanoacrylate monomer, epoxy group-containing acrylic monomer, acrylic acid ester monomer, wherein, the silver compound represented by the formula 1 is one or a mixture of two or more selected from the group consisting of silver oxide, silver thiocyanate, silver cyanide, silver cyanate, silver carbonate, silver nitrate, silver nitrite, silver sulfate, silver phosphate, silver perchlorate, silver tetrafluoroborate, silver acetylacetonate, silver acetate, silver lactate, silver oxalate and a derivative thereof, the ammonium carbamate-based compound of the formula 2 is one or a mixture of two or more selected from the group consisting of ethylammonium ethylcarbamate, isopropylammonium isopropylcarbamate, n-butylammonium n-butylcarbamate, isobutylammonium isobutylcarbamate, t-butylammonium t-butylcarbamate, 2-ethylhexylammonium 2-ethylhexylcarbamate, octadecylammonium octadecylcarbamate, 2-methoxyethylammonium 2-methoxyethylcarbamate, 2-cyanoethylammonium 2-cyanoethylcarbamate, dibutylammonium dibutylcarbamate, dioctadecylammonium dioctadecylcarbamate, methyldecylammonium methyldecylcarbamate, hexamethyleneiminium hexamethyleneiminecarbamate, morpholinium morpholinecarbamate, pyridinium ethylhexylcarbamate, triethylenediaminium isopropylbicarbamate, benzylammonium benzylcarbamate, triethoxysilylpropylammonium triethoxysilylpropylcarbamate and a derivative thereof, the ammonium carbonate-based compound represented by the formula 3 is one or a mixture of two or more selected from the group consisting of ethylammonium ethylcarbonate, isopropylammonium isopropylcarbonate, n-butylammonium n-butylcarbonate, isobutylammonium isobutylcarbonate, t-butylammonium t-butylcarbonate, 2-ethylhexylammonium 2-ethylhexylcarbonate, 2-methoxyethylammonium 2-methoxyetylcarbonate, 2-cyanoethylammonium 2-cyanoethylcarbonate, octadecylammonium octadecylcarbonate, dibutylammonium dibutylcarbonate, dioctadecylammonium dioctadecylcarbonate, methyldecylammonium methyldecylcarbonate, hexamethyleneiminium hexamethyleneiminecarbonate, morpholinium morpholinecarbonate, benzylammonium benzylcarbonate, triethoxysilylpropylammonium triethoxysilylpropylcarbonate, triethylenediaminium isopropylcarbonate and a derivative thereof, and the ammonium bicarbonate-based compound represented by the formula 4 is one or a mixture of two or more selected from the group consisting of isopropylammonium bicarbonate, t-butylammonium bicarbonate, 2-ethylhexylammonium bicarbonate, 2-methoxyethylammonium bicarbonate, 2-cyanoethylammonium bicarbonate, dioctadecylammonium bicarbonate, pyridinium bicarbonate, triethylenediaminium bicarbonate and a derivative thereof.
