摘　　要：采用实验室自制的雷达吸收涂层,探究雷达吸波涂层在紫外环境中的老化行为,开展了紫外光老化进行加速老化实验。通过SEM和XPS分析表明,雷达吸波涂层吸收剂氧化产生了细小均匀的颗粒为Fe2O3,通过EIS分析表明,环氧树脂老化过程中产生了羧基阴离子,经过了紫外光的加速老化实验,雷达吸波涂层的表面粗糙度从0.84μm上升到了1.17μm。Laboratory-made radar absorption coatings were used to investigate the aging behavior of radar absorbing coatings in ultraviolet environment, and an accelerated aging experiment was carried out by ultraviolet aging. The SEM and XPS analysis showed that the radar absorbing coatings absorber oxidized to produce fine and uniform particles of Fe2 O3. The EIS analysis showed that carboxyl anion was generated during the aging of epoxy resin, and an accelerated aging experiment was carried out with ultraviolet light. The surface roughness of radar absorbing coatings increased from 0.84 μm to 1.17 μm.
