• Abstract: Polyurea (PU) is one of the research hotspots with a growing interest in modern coating materials, with the goal of research being complex coatings and the possibility of changing their characteristics and properties during the manufacturing process. The synthesis of polyureas requires step-sized polymerization by the reaction of isocyanate monomers/prepolymers and polyamines, with each component having at least two functions. A wide range of excellent properties, such as durability and high resistance to atmospheric, chemical and biological factors, make this polymer an excellent choice for practical applications. Polyureas are a special material because they contain both a rigid part, which is due to the use of diisocyanates and the formation of hydrogen spots, and a flexible part, which is due to the chemical structure of polyamines. In this paper, the classification, microstructure and macroscopic properties of polyurea and its application in various aspects are reviewed. 人们对现代涂层材料的兴趣日益浓厚，研究的目标是复杂的涂层以及在制造过程中改变其特征和性能的可能性，聚脲（PU）就是研究热点之一。聚脲的合成需要通过异氰酸酯单体/预聚物和多胺的反应进行步长聚合，每一组分至少具有两种功能。广泛的优异性能，如耐久性和对大气、化学和生物因素的高抗性，使这种聚合物成为实际应用的杰出选择。聚脲是一种特殊的材料，因为它们既包含刚性部分，这是由于二异氰酸酯的使用和氢点的形成，也包含柔性部分，这是由于多胺的化学结构。本文综述了聚脲的分类、微观结构与宏观性能关系及其在各个方面的应用。
