摘要:

用常压空气介质阻挡放电等离子体在PBO纤维表面接枝聚氨酯，研究了上浆剂对接枝反应的影响。对接枝改性后的PBO纤维的XPS分析结果表明，等离子体接枝聚氨酯改性使PBO纤维表面的化学组成发生了很大的变化。与DBD单独处理相比，接枝改性后的PBO纤维出现了更多的羧基，其提高值为64%~189%(不含上浆剂时)、102%~184%(含上浆剂时)，为其与其它材料之间的化学键合提供了条件。接枝反应不受上浆剂的影响，等离子体接枝反应破坏了表面PBO分子的噁唑环。通过ATR-FTIR发现，带上浆剂的PBO纤维接枝前后噁唑环的特征峰没有变化，因此在近表面尺度的PBO分子没有破坏的依据；而在不含上浆剂的接枝改性PBO纤维上能检测到噁唑环的破坏，表明上浆剂能阻止等离子体对纤维近表面层的破坏。

Abstract：

Polyurethane was grafted onto the surface of domestic poly-p-phenylene benzobisoxazole (PBO) fiber by atmospheric air dielectric barrier discharge plasma, and the effect of sizing agent on grafting reaction was invetigated. The results of XPS analysis show that the surface chemical composition of PBO fiber modified by plasma grafting polyurethane changed greatly. Compared with the simple air dielectric barrier discharge plasma treated one, the PBO fiber modified by plasma grafting polyurethane had more carboxyl groups, and of which the increment for the later one was 64%~189% (without sizing agent) and 102~184% (with sizing agent) respectively. Sizing agent cannot affect the grafting reaction, and the oxazole ring of PBO was destroyed by plasma grafting reaction. However, ATR-FTIR characterization of PBO fibers with sizing agent showed that the oxazole ring characteristic peaks did not change before and after grafting, so there was no evidence for the destruction of PBO molecules in the near surface. The damage of oxazole ring was detected on the grafted PBO fiber without sizing agent. Thus the sizing agent can prevent the damage of DBD plasma on the near surface of the fiber.

Key words： PBO fiber plasma graft surface modified chemical
