In this paper,the microstructure morphology,damping principle,synthesis and classification of latex interpenetrating polymer networks(LIPN)are introduced. The damping performance influencing factors,the application areas and the research outlook of latex interpenetrating polymer networks are also discussed. The relationship between the damping performance and the structure of LIPN is explained. In the synthesis process,the damping performance is influenced by the crosslinking agent content,ratio of networks,feeding sequence,feeding methods and the filler. LIPN is widely applied in damping coating,leather finishing agent and pigment printing binder. This paper also points out the bottlenecks of current research of latex interpenetrating polymer networks and the future research breakthroughs should focus on new polymerization process,diversity of composition and new characterization methods.%介绍了胶乳互穿网络聚合物的微观结构形态、阻尼原理、合成过程和类别,讨论了其阻尼性能的影响因素,同时对胶乳互穿网络聚合物在不同领域的应用进行了总结,并对胶乳互穿网络聚合物的发展方向进行了展望.指出了胶乳互穿网络聚合物结构与阻尼性能的关系,在其合成过程中,其阻尼性能受到交联剂含量、网络配比、加料顺序、加料方式和填料的影响,其在阻尼涂料、皮革涂饰剂和涂料印花等领域有广泛的应用.同时也指出了目前关于胶乳互穿网络聚合物的研究遇到的瓶颈,未来的研究应从新的聚合工艺、新的表征方法和组成多样性寻求突破.
