Determination of Thermodynmic Surface Characteristics of Carbon Nanotubes via Inverse Gas Chromatography Method
نویسندگان
چکیده
Inverse gas chromatography method is widely used for the characterization of polymers and surfactants that are capable to offer useful information to predict miscibility of polymer composites. However adaption of IGC to carbon nanotubes (CNTs) is still challenging due to many problems arising in establishment and there are only limited reports about CNTs. Thus we researched the thermodynamic surface characteristics of CNTs study. And we confirmed that the IGC method can be successfully applied for various CNTs to determine unknown thermodynamic surface characteristics, including solubility parameter in particular.

A fiber coating from polyaniline (PANI) was electrochemically prepared and employed for Solid phase micreoextraction (SPME). The PANI film was directly electrodeposited on the platinum wire surface using cyclic voltametry (CV) technique. The same method was applied for the preparation of SPME fiber coated by polyaniline multiwalled carbon nanotubes (PANI/MWCNTs) composite. The concentration of ...

The synthesis of the gas chromatography stationary phase by molecular self-assembly of carbon nanotubes (CNTs) via a novel ethanol chemical vapor deposition process is presented. A major advantage is that ethanol was found to be an excellent carbon source that generated highly pure multiwalled carbon nanotubes with very little nontubular carbon impurities. The nanotubes were not vertically alig...
