Abstract
The functionalization of multi-walled carbon nanotubes in He:O plasma is investigated. It is shown that plasma treatment leads to the removal of defective outer graphene layers and their fragments due to oxidation. It is established that the surface of functionalized multi-walled carbon nanotubes contains numerous uncoordinated carbon atoms and oxygen-containing functional groups. The preservation of the structure of the internal graphene layers of nanotubes and the formation of broken chemical bonds ensure a decrease in electrical resistance. At the same time, there is a narrowing of the distribution of electrical resistance values of nanotube ensembles.
等离子体 He:O 处理对多壁碳纳米管结构的影响
摘要 研究了 He:O 等离子体中多壁碳纳米管的功能化。研究表明，等离子体处理可去除石墨烯外层的缺陷及其因氧化而产生的碎片。研究证实，功能化多壁碳纳米管的表面含有大量未配位的碳原子和含氧官能团。纳米管内部石墨烯层结构的保持和断裂化学键的形成确保了电阻的降低。与此同时，纳米管组合的电阻值分布也会缩小。

期刊介绍：
Technical Physics Letters is a companion journal to Technical Physics and offers rapid publication of developments in theoretical and experimental physics with potential technological applications. Recent emphasis has included many papers on gas lasers and on lasing in semiconductors, as well as many reports on high Tc superconductivity. The excellent coverage of plasma physics seen in the parent journal, Technical Physics, is also present here with quick communication of developments in theoretical and experimental work in all fields with probable technical applications. Topics covered are basic and applied physics; plasma physics; solid state physics; physical electronics; accelerators; microwave electron devices; holography.
