碳纳米管sem多大倍数

20-100万倍。碳纳米管，又名巴基管，是一种具有特殊结构（径向尺寸为纳米量级，轴向尺寸为微米量级，管子两端基本上都封口）的一维量子材料。碳纳米管sem20-100万倍之间连续可调，有很大的景深，视野大，成像富有立体感，可直接观察各种试样。

The main purpose is to research and experiment multi-walled carbon nanotubes (MWCNTs) / polycarbonate (PC) resin composite materials, the preparation methods and properties.

In order to improve the multi-walled carbon nanotubes and compatibility of resin, improve the polycarbonate multi-walled carbon nanotubes and polycarbonate resin, using the interface properties of sulfuric acid multi-walled carbon nanotubes surface modification. Using the infrared spectrum, X-ray photoelectron spectroscopy and thermogravimetric analysis of modified carbon nanotubes were the experimental data obtained will made by acid treatment of graph, the different time multi-walled carbon nanotubes are compared. Results show that the length of time, acid treatment effect of multi-walled carbon nanotubes, acid treatment time multi-walled carbon nanotubes were introduced in more active group, also can save the original carbon.

This experiment with solution for blending multi-walled carbon nanotubes/polycarbonate resin composites, use of composite FESEM microstructure observation. Will composite spinning and pure polycarbonate resin spinning. Results show that the polycarbonate resin spinnability, low multi-walled carbon nanotubes/polycarbonate resin composites is not suitable for spinning. Will multi-walled carbon nanotubes/polycarbonate resin composite pressure due to insufficient pressure molding process of mould effect is not ideal. Because the pressure by moulding machine, unstable, cause diaphragm contains a lot of bubbles.

整个实验的关键是合成碳纳米管费事,所以直接外购是可以的,深圳有一家企业是批量生产碳纳米管,这样可方便购得大量的碳纳米管,然后在碳纳米管上沉积CuO、Fe2O3就可以了.后面这一步是很简单的,但还要对碳纳米管表面进行改性,然后再浸渍硝酸盐,氮气...9731
