    Fabrication of Low-Density Perdeuterated p-Divinylbenzene Foams

    • 摘要: 通过魏梯希-霍恩(WittigHorneew)反应合成了氘代对二乙烯基苯,并利用红外、核磁共振和质谱对其结构及氘代率进行了表征。同时利用高内相乳液法(HIPE)制备了低密度全氘代对二乙烯基苯泡沫。泡沫氘代率、形貌结构和力学性能表征结果表明,材料氘代率为95%,密度为25 mg/cm3时平均孔径为6 μm,弹性模量为2.58 MPa。

       

      Abstract: Deuterated polymer foams as a type of inertial confinement fusion (ICF) target material can be widely used in high-gain, high-density compression fusion targets. In this paper, the deuterated p-divinylbenzene was synthesized by the Wittig-Horneew reaction firstly. The structure of deuterated p-divinylbenzene was confirmed by FT-IR, 1H NMR and mass spectrum. Moreover, the deuterated ratio was analyzed by 1H NMR. After that, with the deuterated p-divinylbenzene, the low density perdeuterated polymer foams were fabricated by high internal phase emulsion. The characterization results show that the deuterated ratio of foams is 95%, the average pore size is about 6 μm and the Young’s modulus is about 2.58 MPa when the density of the foam is about 25 mg/cm3.
