摘　　要：Pickering乳液由于具有独特的界面粒子膜、环境响应性等优势,在化工新型材料和催化材料领域获得广泛应用。本文对Pickering乳液稳定机理进行综述,指出影响Pickering乳液稳定性的3个关键因子分别为界面张力、三相接触角和粒子粒径,阐明了固体颗粒表面润湿性、固体颗粒浓度、水相电解质、水相pH值、油水相体积比等因素通过固体颗粒界面膜理论和三维黏弹粒子网络机理对Pickering乳液稳定性的影响。In recent years, great attention was paid to the Pickering emulsion in the field of new chemical materials and catalytic materials due to its unique interfacial particle layer and stimuli-responsiveness. In this paper, the stabilization mechanism of the Pickering emulsion is reviewed. Three key factors are identified： the interfacial tension, the triple-phase contact angle, and the particle grain size. The influential factors of the Pickering emulsion stability are comprehensively discussed, including the wettability of particles, the particle concentration, the electrolyte in the aqueous phase, the aqueous pH, and the oil/water volume ratio, based on the mechanical barriermechanism and the three-dimensional viscoelastic particle network mechanism.
