The rapid development of radar detection technologies has sparked interest in electromagnetic wave (EMW) absorbing materials for information security and the survivability of military weapons. To date, various EMW absorbing materials, including conductive polymers, dielectric loss materials, and magnetic loss-materials , have been developed. However, owing to the high humidity and salt spray conditions in the marine environment, EMW absorbing coating used on equipment must also exhibit anti-corrosion performance. Therefore, multifunctional materials with excellent anti-corrosion properties and EMW absorption performance are essential.
A team of material scientists led by Jingdezhen Ceramic University in Jingdezhen, China recently outlined the state of low-temperature synthesis of medium-entropy spinel oxide powders with electromagnetic wave-absorbing and anti-corrosion properties to advance research in the field.
The team published their research paper in Nano Research on June 30, 2026.
Because traditional electromagnetic wave absorbing materials are prone to corrosion in salt spray environments such as those in the ocean, and eventually lead to material failure, it is necessary to quickly replace them with materials that possess dual wave absorption capabilities and anti-corrosion properties.
The team of Yongqing Wang professor and Junjie Qian teacher discovered that when absorbing wave powder materials were doped into EP and then formed into a coating, they also had anti-corrosion properties.
“In this research paper, we present a summary of the work carried out by our research team in developing meso-entropy spinel oxides based on low-temperature synthesis, which possess electromagnetic wave absorption and anti-corrosion properties. These materials are intended for use in marine environments. The paper focuses on their design, manufacturing process, electromagnetic wave absorption properties, and anti-corrosion properties, among other features.” Said Junjie Qian, the corresponding author of this research paper, a teacher in the school of Materials Science and Engineering at Jingdezhen Ceramic University.
The evaluation criteria for absorbing materials are to have a wide effective absorbing bandwidth and a relatively low reflection loss value.
“The results indicate that the obtained urchin-shaped MEOs microspheres exhibit excellent EMW absorption performance with an RL min of −64.05 dB and an EAB that can reach 7.35 GHz by adjusting the hydrothermal reaction time. Owing to their excellent anti-corrosion performance, the (NiZnCuMn)Co 2 O 4 MEOs have potential applications in marine environments.” Said Yongqing Wang, the other corresponding author of this research paper, professor in the school of Materials Science and Engineering at Jingdezhen Ceramic University.
“After being coated, the coating was subjected to electrochemical-related tests using an electrochemical workstation. The tests were conducted by immersing in 3.5wt% for different periods of time for comparison.” Said Dandan Ma, first author of this paper, doctoral student in the school of Materials Science and Engineering at Jingdezhen Ceramic University. And she also is a teacher in the school of Materials Science and Engineering at Sichuan University of Science & Engineering, a member in Material Corrosion and Protection Key Laboratory of Sichuan province.
