Carbon Nanotubes

Carbon Nanotubes (CNT)

Carbon nanotubes (CNTs) offer extraordinary properties that redefine possibilities across diverse industries.

Structurally, CNTs resemble cylindrical tubes composed of carbon atoms arranged in hexagonal patterns. While CNTs can occur naturally, such occurrences are rare, and the majority are synthesized.

Their exceptional electrical conductivity, mechanical strength, and thermal stability make them ideal candidates for developing high-performance electronics, lightweight composites, and advanced sensors.

By having the capability to engineer CNTs, it becomes possible to exert precise control over their properties, which creates countless possibilities for their application. From electronics and aerospace to healthcare and environmental remediation, CNTs find utility in an array of fields.

Characterizing Single-Walled Carbon Nanotubes

In this joint webinar, Adam Gilmore and Jeffrey Bodycomb will discuss characterizing single-walled carbon nanotubes using fluorescence and particle analysis.

Carbon nanotubes application notes

EEMs are compiled by HORIBA Jobin Yvon’s Nanosizer® software. A double convolution algorithm (U.S. pat. pending) in the software simultaneously computes excitation and emission wavelength coordinate line shapes for each species within minutes; contributions from all spectral bands in a region of interest are found.

Better Data on Carbon Nanotubes with the NanoLog

Improvements to the HORIBA Scientific Nanolog®, already the best spectrofluorometer for exploration of single-walled carbon nanotubes (SWCNTs), render it even more suitable for this application.

Fluorescence Spectra from Carbon Nanotubes

Single-wall carbon nanotubes (SWNTs), consisting of rolled-up single sheets of carbon atoms, have received much attention recently. SWNTs are known to emit in the IR region, and their emission can be used to characterize their diameter and other structural properties.

Characterization of Carbon Nanotubes Using Tip-Enhanced Raman Spectroscopy (TERS)

The use of TERS to reveal the defects density in the structure of CNTs is of interest for a better understanding of the electrical properties of the devices made with such nano-objects. Not only defects concentration but also local chirality changes from the different radial breathing modes, pressure effect and strain distribution can be studied at the single carbon nanotube level through TERS.

Raman has shown a high potential in characterizing the SWCNTs' structure. The correlation between knowledge about structure with physical and chemical properties about the tubes make the technique extremely powerful to control the quality of the SWCNTs for specific applications. Raman spectrometer capabilities like spatial resolution, spectral resolution and excitation wavelength versatility have been examined. Beside Raman, preliminary fluorescence studies are describing the potential of the technique.

Carbon nanotubes (CNT) are attracting attention and being utilized as cutting-edge materials, including battery materials, due to their lightness, strength, and current density resistance. Various applications have been developed based on these characteristics.

Single wall carbon nanotubes (SWCNT’s) have unique mechanical and electronic properties and therefore have attracted much interest. These nanotubes consist of rolled up single sheets of carbon atoms and due to the high aspect ratio and nature of the C-C bonds have unique properties. A number of techniques are necessary to obtain a complete picture of these complex materials.

Carbon nanotubes (CNTs) are thin, light, and flexible string-like materials with a minimum diameter of less than 1 nm that are composed entirely of carbon atoms. Because of their high electrical conductivity, thermal conductivity, and heat resistance, CNTs are being developed for a variety of applications as next-generation materials. On the other hand, CNTs easily aggregate, so it is essential to understand and control the state of aggregation in order to achieve the expected performance.
