细乳液聚合因其体系稳定性高、成核期长、聚合速率适中以及单体不需要通过水相扩散等独特之处而备受关注，随着对细乳液聚合组分、均质技术以及细乳液聚合机理的深入研究，细乳液聚合的应用日益广泛。总结了细乳液的制备过程、稳定机理、体系组成和聚合动力学，综述了近几年细乳液聚合在各个领域的应用研究进展，其中疏水性聚合物乳液、聚氨酯 -丙烯酸酯（ PUA）乳液等可应用于防腐、防水和可剥离涂料，细乳液聚合的应用正向着多功能化发展。

Mini-emulsion polymerization was widely noted for their unique features such as high system stability，long nucleation period，moderate polymerization rate and no diffusion of monomers through the aqueous phase. With the in-depth research on the components of mini-emulsion polymerization，homogenization technology and the mechanism of mini-emulsion polymerization，the application of mini-emulsion polymerization was becoming more and more widespread. The preparation process，stabilization mechanism，system composition and polymerization kinetics of mini-emulsion were summarized in this paper. Additionally，the recent research progresses of mini-emulsion polymerization in various fields of application were reviewed，and hydrophobic polymer emulsions，polyurethane-acrylate（PUA）emulsions，etc. could be applied in anticorrosive，waterproof，and peelable coatings. The application of mini-emulsion polymerization was moving toward multifunctionality.
