Abstract
The electromagnetic shielding properties of thin films comprising different types of carbon nanotubes (CNTs) were analysed in the microwave frequency range (26–36 GHz). A comparative analysis of the shielding properties was achieved for films based on long and short single-, double- and multi-walled CNTs. The experimental results proved that long-length single-walled CNTs demonstrate the highest interaction with the electromagnetic (EM) field, thereby providing the best shielding efficiency. At the same time, double-walled CNTs demonstrate a higher level of absorption ability (50%) along with the overall high EM shielding efficiency (88%), which makes them attractive for using in nanoelectronics screens as they produce the smallest secondary EM pollution.

Progresses in nanoscience and nanotechnology continuously allow developing new applications, including communications and electronics. e development of new ultra-light and low-cost shielding nanomaterials for the microwave frequency range is a current task for improving the reliability of electronic equipment. is is the reason why intensive investigations of the shielding e ect are carried out for new types of composite materials based on graphite, graphene [1], carbon nanotubes [2,3,4] and other llers
Shielding e ectiveness (SE) of carbon nanotubes (CNTs)-based composites depends on the type of polymer matrix and on the characteristics of CNTs such as length [9], diameter [5, 10], and orientation [11]
