摘要
讨论了惯性约束聚变研究中采用化学及物理手段在聚苯乙烯 (PS)材料掺杂卤素、硅、氘等非金属元素以及铁、铬、钛等金属元素的原理和方法。利用硅烷偶联剂对氧化物表面进行了预处理 ,采用本体聚合的方式将氧化物掺杂在PS网络之中 ,简述了它们在ICF中的应用。
One way to diagnose the target conditions during a laser-driven capsule implosion is to incorporate diagnostic dopant atoms in the capsule wall material-polystyrene (PS). In this paper two kinds of doping methods(chemical and physical) are discussed.Conventionally,chemical synthesis route to produce polystyrene-like polymers is possible.It is straightforward to covalently bond nonmetal dopants like bromine,iodine or other halogens onto plystyrene's pendant rings.Deuterated polystyrene with silicon dopant can also be produced. Metals,on the other hand,do not routinely be bonded covalently to nonmetallic atomic structures.Iron, chromium or titanium,however, can form a stable sandwich compound with a pair of cyclopentadienyl rings.As for the low producing rate and cross-linking of the products physical method is a more advantageous doping way.Used as filler particles, metal oxides,treated with coupling agent,can blend with PS.Some examples of making the composites uniformity fitting the use of ICF target are also mentioned.
