dc.description.abstract | 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. | en_US |
dc.description.sponsorship | We are grateful to Dr. Hannah S. Leese for her helpful input and to Dr. Sangsul Lee for the technical assistance for X-ray nano imaging at Pohang Accelerator Laboratory (PAL 7C). Authors thanks the Basic Science Research Program (2020R1A2C2101652, 2016R1A6A1A03013422, 2017H1D8A2032495, and 2018R1C1B5085386) of the National Research Foundation funded by the Ministry of Science, ICT & Future Planning, Korea Environment Industry & Technology Institute through 2020003110007 Project funded by Korea. Adam Clancy would like to thank SCI for funding through the Ramsay Fellowship Memorial Fund. The prepared samples were analyzed on XRD and spectroscopy installed at the Hanyang LINC Analytical Equipment Center (Seoul). The rheological properties of solutions were analyzed on the MARS III rheometer installed at the Electronics and Telecommunications Research Institute (ETRI, Daejeon). Experiments at Pohang Accelerator Laboratory (PAL 4C and 7C) were supported in part by the Ministry of Science, ICT, and Future Planning of Korea and POSTECH. The used MCR-702 was supported in Anton Paar. | en_US |
