【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。更多还原

【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(W1,O,W2) were adopted for the fabrication process. The W1 phase (water) was mixed with a 3wt% Al2O3PS solution in benzenedichloromethane (O phase ) while stirring. The mixed emulsion (W1/O) was then poured into a 5wt% aqueous PVA solution (W2 phase). Benzene and dichloromethane were evaporated from the resultant emulsion (W1/O/W2), and thus solid Al2O3PS composite shells were formed. Parameters of the typical hollow pellets fit in with the requirement of ICF experiments.更多还原
