以自制全氯代苯乙烯单体（氖代率９９％）为原料，以偶氮二异丁腈为引发剂，经自由基本体聚合反应，先制得全氯代聚苯乙烯，最后采用乳液微封装技术制得直径１５０～４５０μｍ、壁厚２～１５μｍ、球形度≥９９．５％、同心度９５％～９８％、表面粗糙度＜３０ｎｍ的ＩＣＦ固体靶用空心微球。介绍了制备工艺，并对全氯代聚苯乙烯分子量及其分布的控制，微球壁内气泡形成机理，微球储存稳定性等进行了初步探讨。 To make perchloro styrene monomers (neon rate of 99%) as raw materials, with azobisisobutyronitrile as initiator, the free radical polymerization, the first chlorinated polystyrene, and finally the use of emulsion micro The hollow microspheres for ICF solid target with the diameter of 150 ~ 450μm, the wall thickness of 2 ~ 15μm, the sphericity of ≥ 99.5%, the concentricity of 95% ~ 98% and the surface roughness of <30nm were obtained by the encapsulation technique. The preparation process was introduced. The molecular weight and distribution of perchlorethylene, the formation mechanism of bubbles in the microsphere wall and the storage stability of microspheres were also discussed.
