Polyaromatic compounds, with terminal functional groups, can be non-covalently bonded to the sidewall of carbon
nanotubes. This architecture preserves the structural, mechanical, electrical, and electromechanical properties of the
CNTs and ensures that an unhindered functional group is available to bond with an extended polymer matrix.
Spectroscopic measurements and high resolution imaging are used to confirm the functionalization and incorporation of
functionalized MWNTs into a nylon 12 matrix.
The preliminary investigation of solid phase microextraction (SPME) as a method for conducting contamination analysis in clean nitrogen streams is presented. The basic operation and the potential advantages of SPME technology are presented for readers unfamiliar with the technique. A detailed description of sample collection and analysis is provided. A discussion of sampling theory and quantification is also included. Results of laboratory experiments and some preliminary field tests are discussed, as well as the direction for future development of the technique.
