“…The sample was sandwiched between two pieces of glass, and shearing force was measured by pulling a piece of glass at a constant displacement rate (100 µm s −1 ) in displacement control mode. Electrical conductivity was measured by a standard four-probe method composing a Keithley 2400 multiple-function source-meter [ 32 ]. Thermal conductivity was calculated by: where α is the thermal diffusivity, C p is the specific heat capacity, and ρ is the density of the sample.…”

Eliminating topological defects to achieve monodomain liquid crystals is highly significant for the fundamental studies of soft matter and building long-range ordered materials. However, liquid crystals are metastable and sensitive to external stimuli, such as flow, confinement, and electromagnetic fields, which cause their intrinsic polycrystallinity and topological defects. Here, we achieve the monodomain liquid crystals of graphene oxide over 30 cm through boundary-free sheargraphy. The obtained monodomain liquid crystals exhibit large-area uniform alignment of sheets, which has the same optical polarized angle and intensity. The monodomain liquid crystals provide bidirectionally ordered skeletons, which can be applied as lightweight thermal management materials with bidirectionally high thermal and electrical conductivity. Furthermore, we extend the controllable topology of two-dimensional colloids by introducing singularities and disclinations in monodomain liquid crystals. Topological structures with defect strength from − 2 to + 2 were realized. This work provides a facile methodology to study the structural order of soft matter at a macroscopic level, facilitating the fabrication of metamaterials with tunable and highly anisotropic architectures.

Fiber-based supercapacitors (F-SCs) have inspired widespread interest in the fields of wearable technology, energy, and carbon neutralization due to their highly deformable flexibility, fast charging/discharging capability, long-term stability, and energy conservation ability. In this review, we summarize the latest developments for fabricating fibrous electrodes of F-SCs where advanced micro two-dimensional (2D) building blocks (e.g., MXene and graphene) are chemically assembled and constructed into ordered mesofibers and multifunctional macrofabrics. Diverse fundamental principles of 2D hybrid nanosheets with respect to surface controls, pseudocapacitive modifications, and microstructural manipulations, promoting rapid electron transfer and charge conduction, are introduced. Additionally, various spinning methods for assembling and fabricating sophisticated fibers with advanced nano/microstructures, including hierarchical skeletons, anisotropic backbones, surface/entire porous frameworks, and vertical-aligned networks, for boosting ionic kinetic transport/storage are presented. Likewise, the structure–activity relationships between the porous structure and electrochemical performance are clarified. Moreover, multifunctional fabrics in terms of high flexibilities/strengths, superior electrical conductivities, and stabilized operations, which realize large energy density, deformable capability, and robust stability under harsh conditions, are emphasized. In particular, the potential power-supply applications, including flexible electronic devices, self-powered functions, and energy-sensor systems, are highlighted. Finally, a short conclusion and outlook, along with the current challenges and future opportunities of next-generation F-SCs, are proposed.

“…The so-called conductive fibers generally refer to the fibers with resistivity below 10 7 Ω cm (200 °C, 65% RH), which can be divided into two categories mainly, intrinsic conductive fibers and composite conductive fibers. Intrinsic conductive fibers refer to the fibers with their inherent conductive ability, such as metal fiber, carbon fiber, conductive polymer fiber, [31] carbon nanotube (CNT) fiber, [32][33][34][35][36][37] graphene fiber (GF), [38][39][40][41][42][43][44][45] etc. The important potential has been demonstrated due to its good conductivity, high mechanical strength, and environmental stability.…”

Fibers and textiles are attractive substrates for constructing wearables, the devices rely on conductive fibers with good stretchability to realize electrical conductivity and mechanical adaptivity. The exploitation of stretchable composite conductive fibers (SCCFs) requires diverse strategies in material options and process methods, tackling the challenge in balancing electrical and mechanical properties for ultrafine fiber, which highly determine the properties and applications. In this article, first the working mechanism and advantages of the SCCFs in wearables is introduced. Second, different conductive fillers as well as their respective incorporation strategies and performance superiorities in fabricating SCCFs are systematically summarized. Third, the integration routes of the conductive fillers in SCCFs are indicated and compared, presenting different fabrication strategies and mechanisms for improving the performance of SCCFs. Thereafter, the typical applications of SCCFs in energy management, sensing, actuators, heaters, and displays are highlighted. Accordingly, the main challenges of SCCFs for wearable applications are indicated, and the possible solutions for challenges tackling are proposed. This review prepared aims to highlight the importance of SCCFs in wearables, and provides insights in terms of mechanism, materials, fabrication, and performance improvement, paving a referable way to promote the innovative exploitation and development of SCCFs, extending the application scenarios.
