摘要
以Al2O3 PS复合材料为原料,采用乳液微封装法制备出掺杂Al2O3的PS空心微球。三相溶液分别是两个水相:蒸馏水(W1相)、5wt%PVA水溶液(W2相)和3wt%Al2O3 PS溶液(O相,苯和三氯甲烷混合物作溶剂)。所得微球表面粗糙度低于50nm。
Polystyrene composite shells doped with aluminum oxide used for inertial confinement fusion CICF) experiments were fabricated with emulsion techniques. Three different phases of solution (W1, O, W2) were adopted for the fabrication process. The W1 phase (water) was mixed with a 3wt% Al2O3-PS solution in benzene-dichloromethane (O phase) while stirring. The mixed emulsion (W1/O) was then poured into a 5wt% aqueous PVA solution (W2 phase). Benzene and dichloromethane were evaporated from the resultant emulsion (W1/O/W2), and thus solid Al2O3-PS composite shells were formed. Parameters of the typical hollow pellets fit in with the requirement of ICF experiments.
