Abstract

The plasma functionalization is an important alternative way to functionalize carbon nanostructures (CNTs). In order to get the optimal parameters for low temperature plasma polymerization the diagnosis and control of plasma is necessary. Radiofrequency (RF) discharge of nitrogen and oxygen are rich in different kind of active species that include positive and negative ions and radicals. In our experiment we use the mass spectroscopy to monitor the positive ion fluxes in different discharge conditions. The origins of different impurity ions and the driving ion- molecule reactions are analyzed according to known kinetic schemes.
