摘要 

通过亲核缩聚法制得三氟甲基基团分别位于主链位置和侧链位置的聚芳醚酮,通过1H-NMR确定了两种聚芳醚酮的结构。分析DSC结果发现,三氟甲基基团位于主链位置的聚芳醚酮的玻璃化转变温度(Tg)为166oC,三氟甲基基团位于侧链位置的聚芳醚酮的玻璃化转变温度(Tg)为139oC,因主链的三氟甲基增加了主链的刚性,使得三氟甲基基团位于主链位置的聚芳醚酮具有更高的玻璃化转变温度。三氟甲基基团相对位置不同的聚芳醚酮材料的5%热失重温度均在490oC以上,都表现出良好的热稳定性。分析水接触角结果发现,三氟甲基基团位于主链位置的聚芳醚酮的水接触角为91o,三氟甲基基团位于侧链位置的聚芳醚酮的水接触角为113o,因三氟甲基基团位于侧链位置的聚芳醚酮的氟原子在经过高温处理后更易向薄膜表面迁移,薄膜表面的表面能降低,表现出更加优异的疏水性能。

Abstract: 

The poly(aryl ether ketone) containing trifluoromethyl in the main chain (m-F-PAEK) and side chain (s-F-PAEK) were respectively synthesized through nucleophilic polycondensation. The structures of the two poly(aryl ether ketone)s were determined by 1H-NMR. DSC studies showed that Tg of the m-F-PAEK was 166oC, and that of the s-F-PAEK was 139oC. The higher Tg of m-F-PAEK was due to the trifluoromethyl in the main chain which had increased the rigidity. Moreover, the 5% thermal weightless temperature of the two polymers was above 490oC, indicating their good thermal stability. Water contact angle results showed that the water contact angle of the m-F-PAEK and the s-F-PAEK was 91o and 113o, respectively. The result demonstrated that s-F-PAEK had better hydrophobic performance than m-F-PAEK. This was because that the fluorine atoms of the s-F-PAEK more likely to migrate to the surface of the film after high temperature treatment, which decreased the surface energy further.
