纳米Fe3O4/氟碳树脂磁场诱导自组装抗反射薄膜的制备及表征

为了获得高度取向的阵列材料,以水热合成的纳米Fe₃O₄磁性颗粒为功能物质,氟碳树脂为薄膜基体,在磁场作用下定向生长成具有磁性针状阵列结构的自组装抗反射薄膜,并考察不同Fe₃O₄含量对磁性阵列结构的影响;利用体视显微镜和扫描电镜（SEM）对薄膜表面结构进行了表征;采用紫外可见近红外分光光度计（UV/Vis/NIR）来表征自组装薄膜的反射率。结果表明:随着Fe₃O₄含量的增加,阵列高度逐渐增高;当粉体质量分数为10%时,阵列的间距为300～600μm,阵列中单个针状结构中间的直径约为100μm;薄膜表面的阵列结构对于反射率的降低有明显效果

Fabrication and optical properties of nano-Fe3O4/fluorocarbon self-assembled antireflection films under magnetic field

To obtain the materials with highly ordered arrays,the self-assembled antireflection films with oriented needlelike arrays under magnetic field were obtained by taking Fe₂O₄ nanoparticles prepared by the hydrothermal method as the functional material and fluorocarbon resin as film matrix.The influences of Fe₃O₄ content on the structures were discussed.The stereoscopic microscope and scanning electron microscope （SKM）were used to characterize the structures of the film surface.The optical properties were tested by ultraviolet-visible-near infrared spectrophotometer（UV/Vis/NIR）.Results showed that the height of arrays became higher as the content of Fe₃O₄ increased.When the content was 10%,the distance of arrays was 300-600μm,and the diameter in the middle of single needle was about 100μm.The reflectance of self-assembled films could be significantly reduced due to the structures of arrays.
