New water-soluble nanocomposites with cobalt oxide nanoparticles (CoONPs) in a poly(1-vinyl-1,2,4-triazole) (PVT) matrix have been synthesized. The PVT used as a stabilizing polymer matrix was obtained by radical polymerization of 1-vinyl-1,2,4-triazole (VT). The polymer nanocomposites with CoO nanoparticles were characterized by ultraviolet-visible, Fourier-transform infrared spectroscopy, atomic absorption spectroscopy, transmission electron microscopy, dynamic light scattering, gel permeation chromatography, and simultaneous thermogravimetric analysis. The resulting polymer nanocomposites consist of spherical isolated cobalt nanoparticles with a diameter of 1 to 13 nm. The average hydrodynamic diameters of macromolecular coils are 15-112 nm. The cobalt content in nanocomposites ranges from 1.5 to 11.0 wt.%. The thermal stability of nanocomposites is up to 320 °C.
已合成了一种新型的水溶性纳米复合材料，该材料是在聚（1-乙烯基-1,2,4-三唑）（PVT）基质中含有氧化钴纳米颗粒（CoONPs）。用作稳定聚合物基质的PVT是通过1-乙烯基-1,2,4-三唑（VT）的自由基聚合反应制得的。通过紫外可见光谱、傅里叶变换红外光谱、原子吸收光谱、透射电子显微镜、动态光散射、凝胶渗透色谱以及同步热重分析对含有CoO纳米颗粒的聚合物纳米复合材料进行了表征。所得的聚合物纳米复合材料由直径为1至13nm的球形孤立钴纳米颗粒组成。大分子线圈的平均流体动力学直径为15 - 112nm。纳米复合材料中的钴含量范围为1.5至11.0重量％。纳米复合材料的热稳定性高达320℃。
