• 摘要： 人們對現代涂層材料的興趣日益濃厚，研究的目標是復雜的涂層以及在制造過程中改變其特征和性能的可能性，聚脲（PU）就是研究熱點之一。聚脲的合成需要通過異氰酸酯單體/預聚物和多胺的反應進行步長聚合，每一組分至少具有兩種功能。廣泛的優異性能，如耐久性和對大氣、化學和生物因素的高抗性，使這種聚合物成為實際應用的杰出選擇。聚脲是一種特殊的材料，因為它們既包含剛性部分，這是由于二異氰酸酯的使用和氫點的形成，也包含柔性部分，這是由于多胺的化學結構。本文綜述了聚脲的分類、微觀結構與宏觀性能關系及其在各個方面的應用。
• 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.
