Treatment of Carbon Nanotube Thread in a Microwave Magnetic Field

The effect of a high-power microwave magnetic field on carbon nanotube (CNT) thread is investigated. The thread produced by dry spinning of the CNTs synthesized by a floating catalyst CVD method was treated with a magnetic field in the microwave system operating at a fixed 2.45 GHz frequency. The study of the structure and elemental composition of the pristine CNT thread and the CNT threads subjected to a 1.3 kW microwave magnetic field is provided. An explanation of the paramagnetic behavior of CNT threads and an analysis of the interaction of threads with microwave radiation are presented.
