以双酚芴单体和全氟联苯为原料,通过亲核取代反应,在较低温度(120℃)下直接聚合,得到了一种高分子量的含芴部分含氟的聚芳醚,并用1H-NMR进行表征.合成的聚合物具有好的热稳定性,玻璃化温度达到271℃,5%的热失重为420℃.这些聚合物能溶于四氢呋喃、二氯甲烷、氯仿和DMAC等常见的有机溶剂,通过溶液浇注的方法制备出光滑、柔韧的膜,并利用表面接触角(CA)对膜材料的表面性能进行了表征.用氯仿制备膜的接触角为102°,而用四氢呋喃制备膜的接触角为107°,接触角接近聚四氟乙烯(112°),具有较好的憎水性.
Using bisphenol fluorene monomer and perfluorobiphenyl as raw materials, a high molecular weight fluorine-containing polyarylene containing fluorene is obtained by nucleophilic substitution reaction and direct polymerization at a relatively low temperature (120 ° C) 1H-NMR. The synthesized polymer has good thermal stability, the glass transition temperature reached 271 ℃, 5% of the thermal weight loss of 420 ℃. These polymers can be dissolved in tetrahydrofuran, methylene chloride, chloroform and DMAC common , And the surface of the film was characterized by surface contact angle (CA). The contact angle of the film was prepared with chloroform to 102 °, and the film was prepared with tetrahydrofuran The contact angle of the film is 107 ° and the contact angle is close to that of Teflon (112 °), which has good hydrophobicity.
