High torsional strength fibers are of practical interest for applications such as artificial muscles, electric generators, and actuators. Herein, we maximize torsional strength by understanding, measuring, and overcoming rheological thresholds of nanocarbon (nanotube/graphene oxide) dopes. The formed fibers show enhanced structure across multiple length scales, modified hierarchy, and improved mechanical properties. In particular, the torsional properties were examined, with high shear strength (914 MPa) attributed to nanotubes but magnified by their structure, intercalating graphene sheets. This design approach has the potential to realize the hierarchical dimensional hybrids, and may also be useful to build the effective network structure of heterogeneous materials.

高抗扭强度纤维对于人造肌肉、发电机和执行器等应用具有实际意义。在此，我们通过了解、测量和克服纳米碳（纳米管/氧化石墨烯）涂料的流变阈值来最大化扭转强度。形成的纤维在多个长度尺度上表现出增强的结构、改进的层次结构和改进的机械性能。特别是，我们检查了扭转性能，其高剪切强度（914 MPa）归因于纳米管，但由于其结构和嵌入的石墨烯片而被放大。这种设计方法有可能实现分层维度混合，也可能有助于构建异质材料的有效网络结构。
