A polyurethane (PU) is a multifunctional polymer prepared by using more than two types of monomers. The unique properties of PU come from monomers, thus broadening the applicability of PU in many different sectors. The properties can be further improved by using many nanoparticles. Different metal oxides as nanoparticles are also widely used in PU materials. ZnO is a widely used inorganic metal oxide nanoparticle for improving polymer properties. In this review article, the techniques to prepare a PU/ZnO composite are reviewed; the key protective properties, such as adhesive strength and self-healing, and applications of PU/ZnO composites are also highlighted. This review also highlights the PU/ZnO composite's current challenges and future prospects, which will help to broaden the composite practical application by preparing environmentally friendly composites.
聚氨酯（PU）是一种由两种以上单体制备的多功能聚合物。PU的独特性能源于单体，从而拓宽了PU在许多不同领域的适用性。通过使用许多纳米颗粒可以进一步改善其性能。不同的金属氧化物作为纳米颗粒也广泛应用于PU材料中。氧化锌（ZnO）是一种广泛用于改善聚合物性能的无机金属氧化物纳米颗粒。在这篇综述文章中，对制备PU/ZnO复合材料的技术进行了综述；还重点介绍了关键的防护性能，如粘合强度和自愈性能，以及PU/ZnO复合材料的应用。本综述还强调了PU/ZnO复合材料当前面临的挑战和未来前景，这将有助于通过制备环保型复合材料来拓宽该复合材料的实际应用。
