摘　　要：以E-44环氧树脂、十三氟辛醇、2,4-甲苯二异氰酸酯(TDI)和马来酸酐(MA)为原料,通过溶液聚合法合成了水性UV固化氟醇改性环氧树脂预聚体(F13–EMA),利用FT-IR对其结构进行了表征。与不含氟环氧顺丁烯酸酯(EMA)进行比较,研究了F13–EMA的热学、光学与力学性能以及疏水、疏油性能。结果表明,与EMA相比,F13–EMA光固化时间近似,硬度和附着力稍有下降,但热稳定性提高,其冲击强度由75 kg·cm提高到120 kg·cm,表面自由能由45.6 mN/m降低到17.1 mN/m,对水、乙二醇的接触角分别由40°、35°增大到104°和65°。水性UV固化F13–EMA膜的疏水、疏油性能大大提高。A water-based UV-curable tridecafluorooctanol modified epoxy resin prepolymer （F13-EMA） was synthesized by solution polymerization with E-44 epoxy resin, 2-（perfluorohexyl）ethanol, 2,4-toluene diisocyanate （TDI）, and maleic anhydride （MA）, and characterized by FT-IR. The thermal, optical, and mechanical properties as well as the hydrophobicity and oleophobicity of the F13-EMA were studied and compared with the fluorine-free epoxy maleate （EMA）. The results indicated that as compared with the EMA, the F13-EMA has a nearly the same curing time, slightly decreased hardness and adhesion strength, but higher thermal stability. The impact strength of Fla-EMA was improved from 75 kg·cm to 120 kg·cm, the surface energy reduced from 45.6 mN/m to 17.1 mN/m, and the contact angle increased from 40° to 104° for water and from 35° to 65° for glycol. The hydrophobicity and oleophobicity of the water-based UV-cured Fla-EMA film are enhanced remarkably.
