We investigated the effect of the raw powder properties of carbon nanotube surface coatings on metal powder, with the goal of obtaining high-quality nanocomposites. The mechanical dry coating technique was used to fabricate CNT coatings (guest particles) on the surface of copper (Cu, host) particles using a traditional ball mill and a stirred ball mill. The coatings were produced under various experimental conditions (varying rotation speed and grinding duration, with a ball diameter of 5 mm), and the effect of these conditions on the surface of the powder was determined. The coated surfaces were characterized using scanning electron microscopy and field emission scanning electron microscopy. We compared prolonged milling (48 h) at a low rotation speed (50 rpm), with a short milling period (12 h) at high rotation speed. We found that for the TBM, successful CNT coating was achieved at 50 rpm over 48 h. In contrast, for the SBM, CNT coatings were obtained after a short milling period (12 h) at low rotation speed (50 rpm).

我们研究了碳纳米管表面涂层的原料粉末性能对金属粉末的影响，目的是获得高质量的纳米复合材料。机械干涂技术用于使用传统的球磨机和搅拌球磨机在铜（Cu，主体）颗粒的表面上制造CNT涂层（客体颗粒）。在各种实验条件下（旋转速度和研磨时间变化，球直径为5 mm）生产涂层，并确定这些条件对粉末表面的影响。使用扫描电子显微镜和场发射扫描电子显微镜对涂覆的表面进行表征。我们比较了在低转速（50 rpm）下的长时间研磨（48 h）和在高转速下的短研磨时间（12 h）。我们发现，对于TBM，在48小时内以50 rpm成功完成CNT涂层。相反，对于SBM，在短研磨时间（12小时）后以低转速（50 rpm）获得CNT涂层。
