【目的】提高聚氨酯丙烯酸酯基体的疏水耐磨性能，拓展其在高端电子领域的应用。【方法】采用甲苯二异氰酸酯（TDI）、聚己内酯二醇（PCL）、八氟戊醇（OFP）和甲基丙烯酸羟乙酯（HEMA）合成了一系列含氟聚氨酯丙烯酸酯（FPUA）树脂，并将树脂与多官能活性稀释剂、光引发剂混合搭配成 UV固化涂料。对不同氟醇用量的树脂及固化后的涂层进行了测试。【结果】一元氟醇 OFP的加入降低了 FPUA涂层的表面张力，使涂层具有优良的疏水性，当 OFP含量为 20%时，水接触角可以达到 99°。OFP的引入使涂层在不同摩擦次数下均具有较好的疏水性，同时具有优异的力学性能，附着力 0级，硬度 2H，耐冲击性 50 cm。【结论】OFP的引入提高了聚氨酯丙烯酸酯的疏水耐磨性，为其在低表面能领域的应用提供了一种可行的思路。

［Objectives］ To enhance the hydrophobicity and wear-resistance of polyurethane acrylate matrix，and expand its application in high-end electronics field.［Methods］ A series of fluorinated polyurethane acrylate（FPUA）resins were synthesized using toluene diisocyanate（TDI）， polycaprolactone diol（PCL），octafluoropentanol（OFP）and 2-hydroxyethyl methacrylate（HEMA），and the resins were then mixed with multifunctional reactive diluents and photoinitiators to form photocurable coatings. The resin with different amount of fluoroalcohol and the cured coating weretested.［Results］The addition of the monofluoroalcohol OFP reduced the surface tension of FPUA coating，which made the coating have excellent hydrophobicity. When the OFP content was 20%，the water contact angle could reach 99° . The introduction of OFP made the coating have good hydrophobicity under different friction times，as well as excellent mechanical properties includingadhesion grade 0，hardness 2H，and impact resistance 50 cm.［Conclusion］The introduction of OFP improved the hydrophobicity and wear-resistant performance of polyurethane acrylate，providing a feasible idea for its application in the field of low surface energy.
