Hydrogen Bond-Driven Hierarchical Assembly of Single-Walled Carbon Nanotubes for Ultrahigh Textile Capacity.

Hydrogen-bond-driven 1D assembly of carbon nanotubes dispersed in organic solvents remains challenging owing to difficulties associated with achieving high oxidation levels and uniform dispersion. Here, we introduced a bioinspired wet-spinning method that utilizes highly oxidized single-walled carbon nanotubes dispersed in organic solvents without superacid or dispersants. By incorporating submicrometer-sized graphene oxide nanosheets, we facilitated the ejection of 1.

All-in-one flexible supercapacitor with ultrastable performance under extreme load.

Fiber-type solid-state supercapacitors are being widely investigated as stable power supply for next-generation wearable and flexible electronics. Integrating both high charge storage capability and superior mechanical properties into one fiber is crucial to realize fiber-type solid-state supercapacitors. In this study, we design a “jeweled necklace”–like hybrid composite fiber comprising double-walled carbon nanotube yarn and metal-organic frameworks (MOFs).
