Summary
This review classifies over 200 papers on single-walled carbon nanotube (SWNT) separation methods. It details techniques like electrophoresis and chromatography for controlling SWNT properties for advanced applications.
Area of Science:
- Materials Science
- Nanotechnology
- Chemistry
Background:
- Single-walled carbon nanotubes (SWNTs) are crucial for nanoelectronics and nanooptics.
- Controlling SWNT structure is essential for their advanced applications.
- Over 200 papers published since 1998 highlight the importance of SWNT separation.
Purpose of the Study:
- To review and classify existing literature on SWNT separation methods.
- To provide a comprehensive overview of techniques used to control SWNT properties.
- To analyze trends in SWNT separation research.
Main Methods:
- Literature review and classification based on separation techniques.
- Categorization of methods into electrophoresis, centrifugation, chromatography, selective solubilization, and selective reaction.
- Summarization of literature in tables detailing separated SWNT characteristics and production methods.
Main Results:
- SWNT separation literature is categorized into five main methods.
- Tables provide detailed information on separated SWNTs (metallic/semiconducting, length, diameter, (n,m) structure, handedness).
- Information on SWNT production processes (CoMoCAT, HiPco, arc discharge, laser vaporization) and chemicals used is presented.
Conclusions:
- The review offers a structured overview of SWNT separation strategies.
- Understanding these methods is key to advancing SWNT applications in nanoelectronics and nanooptics.
