摘要

纳米吸波材料是吸波材料发展的重要方向

本工作制备了氟化镁/钡铁氧体双纳米镀层核径迹孔聚酯薄膜

并研究其雷达波吸波性能。用140MeV32S离子轰击聚酯薄膜

产生潜径迹。经二甲基甲酰胺（DMF）和紫外光敏化后用NaOH溶液蚀刻

使潜径迹变成微米/纳米孔径互通的圆柱形孔。用高温真空蒸发法在径迹孔聚酯样品表面蒸镀100–200nm厚的钡铁氧体/氟化镁薄膜。表面反射测量表明

该双纳米镀层核径迹孔聚酯膜在8–18GHz波段有吸收性能。

Abstract

Nanometer materials are of importance in developing electromagnetic-wave-absorbing materials. In this work

16 μm thick polyester membranes were bombarded by 140 MeV 32S ions from the HI-13 tandem accelerator to produce latent tracks. The bombarded samples were sensitized by DMF and UV light at 360 nm wavelength

before chemical etching by NaOH solution to develop latent tracks into pores in sizes of nanometers or micrometers in full depth of the membrane. The samples were coated with thin layers of barium ferrite and magnesium fluoride by vacuum evaporation. The reflectivity indices were measured at 2–18 GHz. The results indicate that the modified polyester membrane can effectively absorb 8–18 GHz radar waves.
