| 摘 要： | 采用反向乳液聚合方法,以环己烷作为连续相,缓蚀剂钨酸钠的水溶液作为分散相,Span80/OP-10作为复合乳化剂,四乙氧基硅烷(TEOS)作为单体,氨水作为催化剂进行反向乳液聚合,制备了包覆缓蚀剂钨酸钠的纳米SiO2粒子。采用动态光散射(DLS)及扫描电镜(SEM)表征了微胶囊粒子的粒径及分布。结合扫描电镜-能谱法(SEM-EDS)和扫描透射电镜-能谱法(STEM-EDS)表征了微胶囊表面和内部的元素组成。

| Abstract: | Silica particles encapsulated with corrosion inhibitor sodium tungstate was synthesized through reverse emulsion polymerization.In the emulsion polymerization system,cyclohexane was used as dispersion medium,Span80 and OP-10 was used as emulsifier,TEOS was used as monomer,ammonia was used as catalyst.The polydispersity of the particle’s diameter was characterized with dynamic light scattering,and scanning electron microscopy(SEM).The distribution of the corrosion inhibitor sodium tungstate was investigated through scanning electron microscopy-X ray energy diffraction spectroscopy(SEM-EDS) and scanning transmission electron microscope-X ray energy dispersive spectrometer(STEM-EDS).The results indicated that the average diameter of the silica is about 600nm,and the corrosion inhibitor was encapsulated in the silica. |
