Abstract: Polystyrene composite shells doped with aluminum oxide used for inertial confinement fusion (ICF) 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.
