摘要
以环氧树脂、全氟辛酸、丙烯酸等为原料合成了一种可光固化的环氧全氟辛酸酯丙烯酸酯(EFOA)低聚物。利用1H-NMR、IR、元素分析、DSC、TGA、接触角以及凝胶含量法等分析手段对低聚物的结构、氟含量、固化膜的热性能,表面自由能以及光固化过程的影响因素进行了研究。结果表明,与EA/HD-DA光聚合物相比,EFOA/HDDA聚合物具有较好的热稳定性;随着预聚物EFOA/EA/HDDA中EFOA含量的增加,固化膜对水和CH2I2的接触角迅速增大,表面自由能大幅度下降至19.97 mN/m。
A UV-curable fluorinated prepolymer was synthesized by epoxy resin, perfluorooctanoic acid, crylic acid. The chemical structure of fluorinated monomer was confirmed by 1^H-NMR and IR spectrum. The thermal behavior, surface free energy and UV-curing reaction was characterized by TGA, DSC, contact angle and gel conversion. UV-curable polymers （EFOA/HDDA） is good heat stability properties, compared to polymers（EA/HDDA） and the surface free energy of polymer film （EFOA/EA/HDDA） can reduce to 19.97 mN/m（Method： Wu） and contact angle is increasing from 79° to 106° for water and from 46° to 84° for CH2I2.
