Graphene oxide (GO) with extraordinary chemical, thermal and mechanical properties offers possibilities in a variety of applications. Many materials have been fabricated through physical blending of GO with other materials, while, the chemical functionalization of GO has generally been considered challenging. Here, we report the preparation of a novel GO-functionalized fibrous material in which individual compliant GO sheets are cross-linked by PAA chains in a near-vertical fashion. This new fibrous material outperforms many other common fibers in stiffness and strength. Combined with straightforward manufacturing methods, the fibers should find applications in a wide range of areas.
氧化石墨烯（GO）具有非凡的化学、热学和力学性能，在各种应用中具有很大的潜力。许多材料都是通过将 GO 与其他材料进行物理共混来制备的，而 GO 的化学功能化通常被认为具有挑战性。在这里，我们报告了一种新型 GO 功能化纤维材料的制备，其中单个柔顺的 GO 片通过 PAA 链以近乎垂直的方式交联。这种新型纤维材料在刚度和强度方面优于许多其他常见纤维。结合简单的制造方法，这些纤维应该可以在广泛的领域得到应用。
