摘　　要：借助W/O/W多重乳液系统制备了纳米硫酸钡,以此作为水-甲苯乳状液的稳定剂,使硫代乙酰胺和氯化锌在乳状液界面上进行反应,生成纳米硫化锌并包裹在硫酸钡表面,得到质地松软、附着力较强的核壳型纳米复合颜料;并通过FT-IR、SEM、TEM、ED X等手段对其进行了表征。Nano barium sulfate is prepared via the W/O/W muti- emulsion system. The emulsion composecl ot water and toluene so -called Pickering emulsion is synthesized with presence of nano barium sulfate acting as the stabilizer for emulsion. The reaction of thioacetamide with zinc chloride takes place at the interface of the emulsion. The soft core- shell compound nano pigment with good adhesion is formed when nano zinc sulfide deposits and enwraps on the surface of the barium sulfate. The products are characterized by means of FT - IR, SEM, TEM, EDX and et al.
