【摘要】：采用种子微悬浮聚合法,以月桂酸为相变芯材,苯乙烯-二乙烯基苯共聚物为壁材,分别掺杂纳米Fe_3O_4和还原氧化石墨烯(RGO)两种雷达吸波材料(RAM),制备了具有红外微波兼容隐身功能的微胶囊材料(RAM-MCPCM)。采用差示扫描量热仪(DSC)、扫描电子显微镜(SEM)、振动样品磁强计(VSM)和矢量网络分析仪等对材料性能进行了表征。结果表明:RAM-MCPCM微观形貌呈表面微凸球状,仍然具有较高相变潜热;涂层厚度为0.5 mm时,Fe_3O_4-MCPCM[w(Fe_3O_4)=8%]/环氧涂层在5.25 GHz时反射率达到最小值-0.54 d B,RGO-MCPCM[w(RGO)=4%]/环氧涂层在8.8 GHz时反射率达到最小值-1.21 d B,两种涂层在环境温度升高时都具有一定控温作用,具备红外微波兼容隐身性能。
[Abstract]:Seed microsuspension polymerization was carried out with lauric acid as phase change core and styrene divinylbenzene copolymer as wall material. Two kinds of radar absorbing materials, Fe_3O_4 and RGO, were doped respectively. The microcapsule materials with infrared microwave compatible stealth function were prepared. The differential scanning calorimeter (DSC), scanning electron microscope (SEM), and magnetic vibration samples were used to prepare the microcapsule material, which was composed of two kinds of radar absorbing materials, such as Fe_3O_4 and reductive graphene oxide (RGO), respectively. The microcapsule material was prepared by using differential scanning calorimeter (DSC). The properties of the materials were characterized by VSM) and vector network analyzer. The results showed that the microstructures of the microstructures of the Ram-MCPCM were spherical on the surface. There is still a high latent heat of phase transition. When the coating thickness is 0.5 mm, Fe3O4-MCPCM [8%] / epoxy coating has a minimum reflectivity of -0.54 d BGO-MCPCM at 5.25 GHz / epoxy coating has a minimum reflectivity of -1.21 dB at 8.8 GHz. Both coatings have a certain temperature control effect when the ambient temperature increases. Infrared microwave compatible stealth performance.
