Abstract Graphene oxide nanoribbons (GONRs), as a new member of carbon family, attracted extensive attention in industry and science field. It has considered to be as a promising nanomaterial for applications in the field of materials science, energy storage and optics science due to its extraordinary mechanical, electrical and thermal properties. Hence, in this study, we carried out a facile and efficient strategy for preparing poly (phenylene benzobisoxazole) (PBO)/GONRs(PGR) composite fibers via one-pot in situ polycondensation method for enhancement in mechanical and thermal properties. The GONRs sheets in this work were obtained by unwrapping multi-walled carbon nanotubes (MWCNTs) side walls, and then directly reacted with PBO monomer 4,6-diaminoresorcinol(DAR) and covalently grafted on PBO molecular chains. The structure and morphology of GONRs and modified GONRs were well demonstrated by the FT-IR, XPS and TEM analysis for confirming the formation of chemical bond between GONRs and PBO molecular chains. The mechanical and thermal properties of PGR composite fibers were also investigated. It was found that the performance of composite fibers about 32.1% improvement in tensile modulus, 24.2% in tensile strength and 10.5% thermal stability, respectively.

氧化石墨烯纳米带功能化的简便方法及其在聚(对亚苯基苯并双恶唑)复合材料中的应用
摘要 氧化石墨烯纳米带(GONRs)作为碳家族的新成员,引起了工业和科学领域的广泛关注。由于其非凡的机械、电学和热性能,它被认为是一种有前途的纳米材料,可用于材料科学、能量存储和光学科学领域。因此,在本研究中,我们通过一锅原位缩聚法制备聚苯并二恶唑(PBO)/GONRs(PGR)复合纤维,以提高机械和热性能,这是一种简便有效的策略。这项工作中的 GONRs 片材是通过展开多壁碳纳米管 (MWCNTs) 的侧壁,然后直接与 PBO 单体 4,6-二氨基间苯二酚 (DAR) 反应并共价接枝在 PBO 分子链上获得的。FT-IR、XPS 和 TEM 分析很好地证明了 GONRs 和改性 GONRs 的结构和形态,以确认 GONRs 和 PBO 分子链之间形成化学键。还研究了 PGR 复合纤维的机械和热性能。结果表明,复合纤维的性能分别提高了约 32.1% 的拉伸模量、24.2% 的拉伸强度和 10.5% 的热稳定性。
