摘　　要：聚合物涂层具有成本低廉、易于制备、使用方便、种类丰富等优点,被广泛用于运输和基础设施等领域金属材料表面的防腐防污。其中,聚氨酯(PU)是一种具有良好机械性能、耐磨性、耐热性和耐腐蚀性等优异性能的聚合物材料。然而传统PU涂层的耐水性不佳,严重影响其在潮湿环境下的稳定性和使用寿命,因此对PU涂层进行疏水改性以增强其耐水性成为了具有广泛应用前景的研究方向。本文总结了用于PU涂层疏水改性的方法和研究进展,并对其进一步的应用前景进行了展望。Polymer coatings are of particular importance in corrosion and fouling protection of metallic materials in transport and infrastructure industries due to their advantages of low cost,easy preparation,convenient operation and rich variety.Among various polymer coatings,polyurethane(PU)coatings are widely used as surface protection materials for metallic facility because of their excellent mechanical property and strong resistance to abrasion,heat and corrosion.However,the presence of hydrophilic components in the formulation of PU coatings leads to a decrease in hydrophobicity,which seriously restricts their industrial application in humid environment.Therefore,many efforts have been made to develop new modification strategies for PU coatings in order to obtain stable hydrophobic coatings.The review aims to provide insight into the recent advances in hydrophobic PU coatings,and methods that have used to modify and design hydrophobic PU coatings are summarized.Also,the challenges and outlook of hydrophobic PU coatings are discussed.
