Yingxi Xie 在 Grafting carbon nanotubes onto copper fibers using a one-step chemical vapor deposition process 指出传统的 CVD 法 通常分为两步走,第一步先将催化剂和 H2 先加热,然后在引入含碳气 体。这样的方法产量低,他们给出了一种新的合成方法,在铜纤维表面 上生成 CNT, 并且处理过的铜纤维比没...
Whereas meeting product quantity and quality are prime intent in process optimization of materials manufacturing, the application of the more reliable full factorial experiment has not been well-explored in optimization studies of Carbon nanotubes (CNTs) synthesis. In this study, statistical full factoria...
由此,“碳纳米管(CarbonNanombo)"一词正式问 世。 1.1.2碳纳米管的结构 碳纳米管(CarbonNanotubes)也叫作巴基管(BuckyTubues),属于富勒碳系类, 是一种具有径向尺寸为纳米级,轴向尺寸为微米级,管子两端基本上都封El的一维量子 材料,可以看成是由片层结构的石墨卷成的无缝中空的纳米级同轴圆柱体,两端是由富 ...
