In article number 2302686, Jiurong Liu, Zhihui Zeng, and co‐workers report a type of N‐doped carbon nanotube encapsulated CoNi alloy nanocomposites with diverse heterostructures, which deliver excellent electromagnetic wave absorption performance involving a minimum reflection loss of −84.0 dB at the thickness of 3.2 mm and a maximum effective bandwidth of 4.3 GHz.
Developing carbon encapsulated magnetic composites with rational design of microstructure for achieving high‐performance electromagnetic wave (EMW) absorption in a facile, sustainable, and energy‐efficiency approach is highly demanded yet remains challenging. Here, a type of N‐doped carbon nanotube (CNT) encapsulated CoNi alloy nanocomposites with diverse heterostructures are synthesized via the facile,...
