New polymer nanocomposites containing silver nanoparticles, stabilized by hydrophilic copolymers of 1-vinyl-1,2,4-triazole with vinylsulfonic acid sodium salt of different composition, were synthesized. Nanocomposites formation was carried out by the method of chemical reduction of silver ions by sodium borohydride in an aqueous medium in the presence of co-polymer. It was established according to the results of transmission electron microscopy that obtained polymer nanocomposites consist of isolated silver nanoparticles of predominantly spherical shape with a diameter from 2 to 16 nm. It was found that composition of the stabilizing polymer matrix controls such nanocomposites parameters as the polydispersity index of nanoparticles ( D w / D n = 1.44−1.34), hydrodynamic radii of macrocoils (266−1118 nm), and zeta potential (from −35.0 to −74.8 mV).

基于亲水性含氮和硫共聚物的金属聚合物银纳米复合材料：纳米颗粒尺寸的控制

合成了含有银纳米颗粒的新型聚合物纳米复合材料，该复合材料由 1-乙烯基-1,2,4-三唑与不同组成的乙烯基磺酸钠盐的亲水共聚物稳定。纳米复合材料的形成是通过硼氢化钠在水性介质中在共聚物存在下化学还原银离子的方法进行的。根据透射电子显微镜的结果确定，所获得的聚合物纳米复合材料由直径为 2 至 16 nm 的主要为球形的孤立银纳米颗粒组成。研究发现，稳定聚合物基质的组成控制着纳米复合材料的参数，如纳米颗粒的多分散指数（D w / D n = 1.44-1.34）、宏线圈的流体力学半径（266-1118 nm）和 zeta 电位（从-35.0至 −74.8 mV）。
