The construction of stable and efficient nanocomposites with low addition light weight has always been the goal pursued in field electromagnetic wave (EMW) absorption. In this study, Co@CNTs Co nanoparticles (13 nm) nanoconfined carbon nanotube (CNT) are successfully synthesized by a simple hydrothermal method phenolic assisted pyrolysis method. degree graphitization CNTs microstructure can be effectively regulated controlling calcination temperature. sample calcined at 700 °C obtain excellent absorption performance filling capacity 10 wt.%: minimum reflection loss (RL) is -41.2 dB effective bandwidth (EAB) reaches maximum width 14.2 GHz. When thickness only 2.2 mm, EAB <-20 8.3 GHz, which most current Co-based absorbers. particular, polarization ferromagnetic coupling behaviors elucidated depth aid simulations using High-Frequency Structure Simulator (HFSS). This work provides new nanoconfinement strategy for constructing as lightweight ultra-broadband absorbing materials EMW protection pollution control.
