Physical, chemical and plasmochemical methods of functionalization and dispersion of carbon nanotubes for their application in electronics

Abstract

Carbon nanotubes (CNTs) have been studied for many years and used in the electronics for the manufacture of various devices. At present, most of the developed practical applications of CNTs in electronics are based on the use of their thin films. There are two methods of deposition thin films of CNTs on different substrates — the deposition by different methods of previously synthesized nanotubes and directly synthesis of CNTs on substrates. The deposition of thin CNTs films according to the first of the above methods is carried out mainly using their dispersions in various liquids. Contemporary physical, chemical and plasma-chemical methods for functionalization and dispersion of CNTs in water and non-aqueous liquids are discussed. Most attention is paid to ultrasonic and plasma techniques, as well as other physical and chemical techniques.
