这篇综述旨在整合关于热喷涂涂层的分散文献，这些涂层具有非电离电磁（EM）波吸收和特定波长的屏蔽，可能适用于各种应用（例如，微波到毫米波、太阳能选择性、光催化、干扰屏蔽、热障-热/发射率）。材料的电磁特性，如介电常数、磁导率、电导率和介电损耗是至关重要的，因为材料可以响应吸收、反射、透射，或者可以在电磁辐射的典型频率下激发表面电磁波。热喷涂是用于沉积涂层的标准工业实践，其中喷涂层通过暴露于高或中等温度和速度的材料的完全或部分熔融的液滴/颗粒的连续冲击形成。然而，作为一个新兴的新的应用现有的热喷涂技术，一些特殊的考虑是必要的，有针对性的发展，涉及相关的表征。确定了与材料选择和涂层制造策略及其对该领域现有实践的影响有关的关键潜在研究领域。该研究显示了原料设计和掺杂方面的研究差距，以及热喷涂涂层覆盖的复杂选择，这对于推进利用其电磁特性的应用至关重要。
This review aims to consolidate scattered literature on thermally sprayed coatings with nonionizing electromagnetic (EM) wave absorption and shielding over specific wavelengths potentially useful in diverse applications (e.g., microwave to millimeter wave, solar selective, photocatalytic, interference shielding, thermal barrier‐heat/emissivity). Materials EM properties such as electric permittivity, magnetic permeability, electrical conductivity, and dielectric loss are critical due to which a material can respond to absorbed, reflected, transmitted, or may excite surface electromagnetic waves at frequencies typical of electromagnetic radiations. Thermal spraying is a standard industrial practice used for depositing coatings where the sprayed layer is formed by successive impact of fully or partially molten droplets/particles of a material exposed to high or moderate temperatures and velocities. However, as an emerging novel application of an existing thermal spray techniques, some special considerations are warranted for targeted development involving relevant characterization. Key potential research areas of development relating to material selection and coating fabrication strategies and their impact on existing practices in the field are identified. The study shows a research gap in the feedstock materials design and doping, and their complex selection covered by thermally sprayed coatings that can be critical to advancing applications exploiting their electromagnetic properties.
