Preparation and properties of dihydroxy poly(p-phenylene benzobisoxazole) (DHPBO) fiber

摘要：

A series of DHPBO fibers were prepared by introducing double hydroxyl polar groups into PBO macromolecular chains. As indicated by FTIR, hydroxyl groups were incorporated into DHPBO polymer chains successfully and intermolecular hydrogen-bonds had been formed. POM revealed the band-textured liquid crystal structure of DHPBO/PPA solution. With the formation of intermolecular hydrogen-bonds, DHPBO fibers exhibited outstanding mechanical properties. On the other hand, the wetting process of water on DHPBO fibers was apparent shorter than on PBO fibers.
