Development of Perdeuterated Polymer Foams for Inertial Confinement Fusion Targets in China

抄録

In this paper, we report the progress made in fabrication of perdeuterated polymer foam materials such as deuterated polystyrene (d-PS), deuterated polyethene (d-PE), and deuterated divinylbenzene (d-DVB) based on the inertial confinement fusion (ICF) research in China. Perdeuterated DVB foams were fabricated using the high internal phase emulsion (HIPE) technique, and perdeuterated PS and PE foams were prepared via the thermally-induced phase separation (TIPS) of polymer solution and freeze-drying. As a result, foams with a deuterium/hydrogen (D/H) ratio of more than 95%, density of 10-200 mg/cm³ , and average porous sizes of 1-20 µm were obtained.
