                 Abstract: Solid nanoparticles instead of traditional surfactants as emulsifier-stabilized Pickering emulsions
                 have the advantages of high coalescence resistance, environmental friendliness and low cost, which exhibit
                 broad application prospects in various fields. The research on the stability of Pickering emulsion by precise
                 regulation and appropriate stimulation and the construction  of stimulus-responsive Pickering emulsions
                 have attracted wide attention. The construction, regulation and application of various Pickering emulsions
                 are reviewed. Firstly, the factors affecting the stability of Pickering emulsion and the surface modification
                 technology of solid particle emulsifier are summarized. Secondly, the response mechanism and performance
                 of various stimuli-responsive Pickering emulsion are introduced. Subsequently, the application of Pickering
                 emulsion is summarized. Finally, the problems and development prospects of Pickering emulsion research
                 and application are analyzed and pointed out.
