将油包水微乳液进一步分散在含有 Pluronic F127 作为空间稳定剂的水相中，形成一种特殊类型的双乳液，称为乳化微乳液 (EME)。内微乳液相由甘油单油酸酯（GMO）、R（+）-柠檬烯、乙醇和甘油制成。使用 SAXS（小 X 射线散射）、PGSE-NMR（脉冲梯度自旋回波 NMR）、电导率和冷冻 TEM（低温透射电子显微镜）成像技术来确认第二乳化步骤后和 EME 老化后内部 W/O 纳米液滴的存在。通过 SAXS 测量和冷冻 TEM 图像观察到没有长程内序的 EME 球形球体。平均大小约为 200-300 nm 的球体在至少 6 个月内保持完整。
A water‐in‐oil microemulsion was further dispersed in an aqueous phase containing Pluronic F127 as a steric stabilizer, to form a specific type of double emulsion termed emulsified microemulsion (EME). The inner microemulsion phase was made from glycerol‐monooleate (GMO), R(+)‐limonene, ethanol and glycerol. SAXS (small x‐ray scattering), PGSE‐NMR (pulse gradient spin echo‐NMR), electrical conductivity, and cryo‐TEM (cryogenic‐transmission electron microscopy) imaging techniques were used to confirm the existence of inner W/O nano‐droplets after second emulsification step and upon EME aging. Spherical globules of EME without long‐range internal order were observed by the SAXS measurements and the cryo‐TEM images. The average globule size of about 200–300 nm remained intact for at least 6 months.
