摘要
用HI-13串列加速器提供的32S离子对聚碳酸酯和CR-39进行了不同密度的辐照,经紫外灯敏化和氢氧化钠蚀刻,样品表面的潜径迹形成具有一定孔径和深度的纳米和微米孔。利用真空蒸发在样品表面镀上金属银和光学材料氟化镁,在可见光波段测量样品镀膜前后的反射率、透过率等光学参数。测量结果表明,固体核径迹技术和镀膜技术可使材料的反射率降低至未处理前的1%以下。
Polyester and CR-39 samples were irradiated with sulphur ion from HI-13 tandem accelerator. Ultraviolet light with wavelength 360 nm was used to sensitize the polymer before chemical etching by NaOH solution with different temperatures and time duration. The latent track was then developed into nanometer to micrometer pore with certain depth. Samples were coated with thin layer of silver and magnesium fluoride using the vacuum evaporator. The reflectivity and transmission index were measured for all polymer samples, untreated and treated with above-mentioned procedure, within the wavelength of visible light. Solid state nuclear track and coating can reduce reflectivity of tested polymer materials greatly, and the reflectivity can be 1% or lower .
