Carbon Nanotubes: Synthesis and Characterization
2018年9月23日 · A remarkable discovery of graphitic particles in the soot of arc-discharge vessel by Iijima marked the birth of new era in nanoscience – “carbon nanotechnology.” Carbon nanotubes (CNTs) represent a distinct group of nanostructures of relatively few nanometers in diameter and micrometers in length with unique physical and chemical properties.
Carbon nanotubes: controlled growth and application
2013年1月1日 · Carbon nanotubes (CNTs) have a one-dimensional tubular structure with nanometer scale diameters and typically micrometer scale lengths. They were formally named in 1991 by Iijima after observing a soot-like product obtained from graphite arcing under a transmission electron microscope (TEM) [1].
Carbon Nanotubes (CNTs) from Synthesis to Functionalized (CNTs…
Carbon nanotubes (CNTs) have emerged worldwide because of their remarkable properties enlarging their field of applications. Functionalization of CNTs is a convenient strategy to tackle low dispersion and solubilization of CNTs in many solvents or polymers.
Testing the resistance of single- and multi-walled carbon
Here, we tested the resistance of 15 structurally different CNTs to chemothermal oxidation at 375 degrees C (CTO-375), a method used to isolate soots from environmental samples. Depending on their structure, CNTs survived CTO-375 in proportions ranging from 26 to 93%.
