Microwave assisted purification of multi-walled carbon nanotubes by potassium permanganate; effect of acid to oxidant molar ratio and treatment time

摘要

Carbon nanotubes (CNTs) benefit from excellent electrical and physical properties and they have attracted considerable interest in different applications like sensors and nanocomposites. Synthesized CNTs usually contain carbonaceous or metallic impurities which limit their beneficial properties. In this study, we experimentally investigate the effects of acid to oxidant molar ratio and treatment time on microwave-assisted purification of MWCNTs.
