摘　　要：以商业化的对羟基苯甲醚为原料,合成了一种新型的含有全氟环丁基芳基醚结构的疏水性聚碳酸酯.该聚合物在不降低材料透明性的前提下,表现出了优异的热稳定性和疏水性,其热分解温度为351℃,涂膜与水的接触角为110°.为了进一步探究全氟环丁基芳基醚结构对聚碳酸酯的性能影响,以含有全氟环丁基芳基醚结构的单体和双酚A单体为原料,合成了一系列具有不同全氟环丁基芳基醚基团含量的聚碳酸酯.通过性能比较可知,将全氟环丁基芳基醚结构引入聚碳酸酯,能够降低聚碳酸酯的分散度,提高其热稳定性和疏水性.A novel hydrophobic polycarbonate containing perfluorocyclobutyl (PFCB) aryl ether was synthesized from commercially available p-methoxyphenol. The polymer exhibited excellent thermal stability and hydrophobicity without reducing the transparency of the material. The thermal decomposition temperature was 351℃ and the contact angle between the film and water was 110°. In order to further explore the effect of PFCB aryl ether structure on the properties of polycarbonate, a series of polycarbonates with different PFCB aryl ether group contents were synthesized from PFCB aryl ether monomer and bisphenol A monomer. By comparing their properties, the introduction of PFCB aryl ether structure into polycarbonate can reduce its dispersion and improve its thermal stability and hydrophobicity.
