| titleOfInvention | Perfluorooctane-based compound and method for preparing perfluorooctane-containing terminated polyaryl ether sulphone |
| abstract | The invention relates to a perfluorooctane compound and a method for preparing perfluorooctane-containing terminated polyaryl ether sulphone and belongs to the technical field of fluororesin preparation. The method comprises the following steps: preparing a perfluorinated compound by adopting Friedel-Crafts acylation; and terminating polyaryl ether sulphone molecular chain (obtained through solution polycondensation) by using the perfluorinated compound, wherein the obtained perfluorooctane terminated polyaryl ether sulphone material has relatively low glass-transition temperature, and relatively low plasticizing condition; and meanwhile, a film material prepared by a solution casting method has a relatively large water contact angle and obvious hydrophobic property, and can be applied to spare parts such as civil and military anticorrosion part coatings and friction bearing valve plates. |
