RESUMEN
To achieve the object of NIF ignition , it is required to prepare high density fuel targets . For DD layer, IR-layering can be used to improve its surface roughness. In this paper, glow discharge polymer (GDP) flat films and capsules were synthesized. The IR absorptive properties of GDP were thoroughly studied by using infrared spectrometer and microscopy while the extinction coefficients of GDP flat film at specific wavelengths were obtained. By comparing absorption properties of flat films and capsules, it is found that thermal treatments can lower the OH content of GDP and thus improve IR layering of DD ice. Finally, the needed IR power of integration sphere were estimated by using data obtained for future DD layering experiments in this paper. The results have laid a solid foundation for the implementation of DD IR layering.
