We prepared high-quality SWCNTs efficiently by a floating catalyst CVD method. Under optimum conditions, the conversion rate of the carbon source to SWCNTs reached 28.8%, and the as-prepared SWCNTs had a purity higher than 95 wt.%. Using the as-prepared high-quality SWCNTs, we spun macroscopic SWCNT fibers with diameters of 10-20 microns by a wet-spinning process. The resulting fibers had a high electrical conductivity of 6.67×10⁶ S/m. We further prepared a SWCNT/Cu core-shell fiber by a combined magnetron sputtering and electrochemical deposition method, which showed an ultra-high specific electrical conductivity of 1.15×10⁴ S m² Kg^-1, 56% higher than Cu [1].

Abstract: Artificial muscle yarns have emerged as a new type of intelligent material and attracted considerable attention. I will give a talk on our recent research progress made in artificial muscle yarns, mainly focusing on addressing the challenges of actuation precision control and actuation feedback. Deploying the faradaic insertion and extraction reactions to drive a CNT yarn muscle allows tetrachloroaluminate ions as a strong but dynamic "locker" to achieve an energy-free high-tension catch state and programmable stepwise actuation. When powered off, the muscle nearly 100% maintained any achieved strokes under loads of 96,000 times the muscle weight. This mechanism allowed the programmable control of stroke steps down to 1%. By wrapping a CNT fiber core in sequence with an elastomer layer, a nanofiber network, and an MXene/CNT thin sheath, we prepared an artificial neuromuscular fiber that achieves a ingenious sense-judge-act intelligent system in an elastic fiber. This would provide a promising solution for closed-loop control for future intelligent soft robots.

Abstract: Flexible wearable thermoelectric fibers and fabrics can collect energy from body heat and power wearable electronic devices by utilizing the temperature difference between human body and the outside environment. They can also be used for thermoelectric refrigeration to control body temperature, and even be used as a thermal sensor to monitor human body temperature in real time. Therefore, based on the large-scale thermal drawing fiber method, we achieved the seamless integration of high-performance inorganic thermoelectric materials and devices into a flexible fiber, and obtained large quantities of amorphous Cu-As-Te-Se, polycrystalline Bi₂Te₃, single crystal SnSe flexible thermoelectric fibers. These new flexible thermoelectric fibers not only overcome the disadvantages from electroplating, dip-dyeing and spinning technology, such as poor thermoelectric performance, low yield, poor mechanical properties, inability to wash, and poor stability caused by the shedding of thermoelectric materials during long-term use. In addition, they can be compatible with modern weaving process, and show the functions of temperature monitoring, thermoelectric power generation and refrigeration, realizing the real sense of flexible wearable thermoelectric fabrics.

Abstract: An optical blackbody is an ideal absorber for all incident optical radiation, and the theoretical study of its radiation spectra paved the way for quantum mechanics (Planck’s law). Herein, we propose the concept of an electron blackbody, which is a perfect electron absorber as well as an electron emitter with standard energy spectra at different temperatures. Vertically aligned carbon nanotube arrays are electron blackbodies with an electron absorption coefficient of 0.95 for incident energy ranging from 1 keV to 20 keV and standard electron emission spectra that fit well with the free electron gas model. Such a concept might also be generalized to blackbodies for extreme ultraviolet, X-ray, and γ -ray photons as well as neutrons, protons, and other elementary particles.

With the rapid change of applications and demands, more structural and functional requirements have been put forward in aerospace, national defense, military, energy, biology and other fields. Carbonene materials (mainly including carbon nanotubes and graphene) have the advantages of low density, high mechanical properties, excellent electrical and thermal conductivity, and are ideal base materials for building next-generation lightweight, high-strength, high-toughness, functional and smart fibers. This report mainly introduces the controlled preparation and application research of carbonene fiber, including the controllable preparation method of carbonene materials, high mechanical properties and multifunctional carbonene fiber, assembly regulation method and property transfer rule of carbonene material in carbonene fiber, as well as the batch preparation technology of carbonene fiber and its application prospect in individual protection and artificial muscle.

Abstract: The preparation of carbon nanotube fibers based on carbon nanotubes has been regarded as an important direction for the development of high-performance fibers in the future, and has broad prospects in cutting-edge fields such as aerospace, military industry eand mobile communication. Crucial  advances have been made in the preparation of carbon nanotube fibers and its multifunctional development towards practical application. However, the properties significantly degraded as numerous carbon nanotubes are assembled into fiber structure, which seriously limited its practical applications. Based on this research status, the report will foucus on fundamental frontier research on carbon nanotubes and carbon nanotube fibers and introduce the latest progress of the research group in the controllable preparation and extreme performance development of ultra-long carbon nanotubes, including the evolutionary growth mechanism of carbon nanotubes, the large-scale controllable preparation of ultra-long carbon nanotubes, and the cross-scale precise assembly and extreme performance development of carbon nanotubes. The prospects and challenges of the further development of carbon nanotubes fibers will also be discussed.

Abstract: With the boom of many new important fields such as flexible electronics, wearable technology and smart health management, it is necessary to make the next-generation electronic devices as thin as possible, which may produce a revolution in the world. However, there remains intrinsic challenges that seem very difficult to be overcome according to the planar structure. To this end, we have explored a new family of fiber energy harvesting devices including perovskite solar cells and fluidic generators, fiber energy storing devices including lithium-ion batteries, lithium-sulfur batteries and metal-air batteries, fiber light-emitting devices and fiber sensors, mainly based on the use of polymers as electrode and active materials. The above fiber devices can be highly integrated into flexible textiles or other structures for large-scale applications with high efficiency and low cost.

Abstract: Aerogels are prepared from sol-gel processing to form the disordered but continuous gel networks and a special drying process to remove the solution components in the gel without changing its gelatinous structure, resulting in the porous, disordered, and low-density solid materials with a nanometer scale continuous network. Fiber is a morphological concept, meaning that the length is larger than the cross-section diameter and has a certain flexibility and robustness. Aerogel fibers are the specific embodiment of aerogel structure in fiber morphology. This presentation will illustrate how to obtain functional inorganic aerogel fibers, polymeric aerogel fibers and graphene aerogel fibers from various nanoscale building blocks, and demonstrate the application of these aerogel fibers in energy, textile and other fields.
