Abstract Synthesis of in-situ composite CNTs/nAl2O3 was studied. CNTs/(5–15 wt. %)nAl2O3 composite was obtained varying the initial Al-contained materials with or without calcination at 700 °C. The CNTs/nAl2O3 nanopowders were comprehensively characterized by XRD, TEM, SEM, EDX, and electron diffraction methods. The morphology of the in-situ synthesized composite CNTs/nAl2O3 was found as a net-shaped structure of nAl2O3 nanofibers uniformly distributed in CNTs with the particle size of less than 30 nm. The synthesized composite CNTs/nAl2O3 is an attractive candidate modifier material for 3D printed silumin.

粉状纳米复合材料“碳纳米管/纳米氧化铝”的原位合成与表征

摘要 研究了原位复合CNTs/nAl2O3 的合成。CNTs/(5–15 wt. %)nAl2O3 复合材料是通过改变初始含铝材料在 700°C 下煅烧或不煅烧而获得的。通过XRD、TEM、SEM、EDX和电子衍射方法对CNTs/nAl2O3纳米粉体进行了综合表征。原位合成的复合CNTs/nAl2O3的形貌为nAl2O3纳米纤维均匀分布在CNTs中的网状结构，粒径小于30nm。合成的复合碳纳米管/nAl2O3 是一种有吸引力的 3D 打印硅铝候选改性材料。
