Application of laser particle size analyzer in carbon nanotubes

1. Influence in the field of electronics

Transistors and integrated circuits

When the diameter of carbon nanotubes is small, their electron mobility is high. For example, single-walled carbon nanotubes have electron mobilities of thousands of square centimeters per volt-second, which allows electrons to move quickly within them. Smaller diameter carbon nanotubes help build high-performance field-effect transistors (FETs). At the nanoscale, carbon nanotubes with small diameters can achieve smaller device sizes, thereby improving the integration of integrated circuits. Just like being able to place more and smaller transistors on a chip, this plays a key role in promoting the development of semiconductor technology to smaller nodes (such as advancing from the traditional micron level to nanometer level or even smaller sizes).

2. Impact in the field of material reinforcement

Composite materials

The length and diameter of carbon nanotubes play a key role when adding them to polymer matrices, such as epoxy resins, to enhance material properties. If the length of carbon nanotubes is longer, a more effective network structure can be formed in the matrix material. For example, long carbon nanotubes, like a "fiber skeleton", can effectively share the stress borne by the matrix, thereby greatly improving the strength and modulus of the composite material.

3. Impact on energy storage

Lithium-ion batteries

For battery electrode materials, carbon nanotubes of appropriate particle size can improve the conductivity of the electrode. If the length of carbon nanotubes is moderate and the diameter is small, a good conductive network can be formed in the electrode material. For example, adding carbon nanotubes to the negative electrode material of lithium-ion batteries can shorten the diffusion path of lithium ions and speed up the charging and discharging speed of the battery. Moreover, smaller diameter carbon nanotubes can provide more lithium ion adsorption sites and increase battery capacity.
