Nanotechnology Breakthrough: Researchers Develop New Electromagnetic Wave Absorbing Materials

Strategic Insights -

Researchers from Shandong University have made a groundbreaking discovery in the field of nanotechnology, developing a new type of electromagnetic wave (EMW) absorbing material that exhibits exceptional performance. The study, published in the journal Diamond and Related Materials, reveals that by introducing metal-organic framework (MOF) derivatives into carbon nanofibers (CNFs), the researchers were able to create a material with complementary loss functions that enhance EMW absorption.

The material, dubbed Cu2Se/CoSe2@CNF-2, achieved a minimum reflection loss of -40.74 dB at a thickness of 1.49 mm, demonstrating optimal impedance matching. In addition, the material showed excellent stealth performance in simulations. The researchers attribute the success of this material to the synergy between the MOF derivatives and CNFs, which balance polarization loss and conductive loss.
