Metal‐polymer nanocomposites have gained increasing attention due to the wide potential applications field. Synthesis of nanoparticles from the gas phase is an intensively studied alternative to the chemical preparation methods. We present a one‐step procedure that combines magnetron‐based gas aggregation cluster source of silver nanoparticles and simultaneous plasma‐enhanced chemical vapour deposition of hexamethyldisiloxane (HMDSO). The key parameter of the process, significantly influencing the morphology and microstructure of studied nanoparticles, was found to be the amount of HMDSO added to the deposition chamber as witnessed by small angle X‐ray scattering and X‐ray diffraction methods combined with transmission electron microscopy and UV–Vis spectrophotometry. The presence of HMDSO in the chamber leads to changes in the size distribution and also in the architecture of prepared nanoparticles. The increasing amount of HMDSO induces the formation of individual core‐shell nanoparticles, chains of core‐shell nanoparticles, and for the highest concentration of HMDSO, the synthesis of multi‐core‐shell nanoparticles. The size of crystallites in the silver cores of nanoparticles decreases with addition of HMDSO, which prevents further aggregation.

金属/等离子聚合物Ag / HMDSO纳米粒子的合成与微观结构研究

金属聚合物纳米复合材料由于其广阔的潜在应用领域而受到越来越多的关注。从气相合成纳米颗粒是化学制备方法的一种深入研究的替代方法。我们提出了一个结合了银纳米颗粒的磁控气体聚集簇源和六甲基二硅氧烷(HMDSO)的同时等离子体增强化学气相沉积的单步骤程序。通过小角度X射线散射和X射线衍射方法与透射电子显微镜相结合,发现该过程的关键参数(显着影响所研究纳米颗粒的形态和微观结构)是添加到沉积室中的HMDSO量。和紫外可见分光光度法。HMDSO在腔室中的存在会导致尺寸分布以及所制备纳米颗粒的结构发生变化。HMDSO含量的增加会诱导单个核壳纳米颗粒,核壳纳米颗粒链的形成,而对于HMDSO的最高浓度,多核壳纳米颗粒的合成。纳米粒子的银核中的微晶尺寸随着HMDSO的添加而减少,这阻止了进一步的聚集。
