Inducing liquid crystallinity in dilute MXene dispersions for facile processing of multifunctional fibers

Abstract

The liquid crystal (LC) phases of two-dimensional (2D) transition metal carbides/nitrides (MXenes) has enabled the production of their unique macro-architectures with ordered microstructure and enhanced properties. However, LC phases in...

Tough and Fatigue Resistant Cellulose Nanocrystal Stitched Ti3C2Tx MXene Films

“…Although we attribute this increased spacing to the presence of CNC, the AFM images suggest that each CNC particle of ≈5 nm thick (Figure 1a) is significantly larger than MXene's interlayer distance and is therefore incapable of intercalating between the layers and significantly increases the d ‐spacing. [ 42 ] This result indicates that MXene‐CNC interactions are most likely through edge‐to‐edge bridging similar to those previously observed for sequentially bridged rGO platelets. [ 28 ] However, it should be noted that the d‐spacing for SBM film remains lower than the MXene‐CNC (≈1.32 nm) or one‐pot (≈1.29 nm) films.…”

Robust Biocompatible Fibers from Silk Fibroin Coated MXene Sheets

“…These results show that despite silk being insulating, the increased MXene interlayer d ‐spacing facilitated electrolyte and ion transport into the fiber. [ 3,13,14,48 ] The M 95 fiber also showed stability over repeated charging and discharging, retaining ≈94% of its capacitance with ≈100% coulombic efficiency even after 10 000 CV cycles (Figure 5f), demonstrating potential high performance energy storage applications.…”

Multiscale Dot‐Wire‐Sheet Heterostructured Nitrogen‐Doped Carbon Dots‐Ti3C2Tx/Silk Nanofibers for High‐Performance Fiber‐Shaped Supercapacitors

“…Therefore, by balancing the ion accessible surface and electrical conductivity, the best energystorage performance is realized. To our knowledge, capacitance level of NCDs-Ti 3 C 2 T x /SNFs fiber has reached one of the largest values compared with the latest literatures, as summarized in Figure 3i and Table S1, including ZIF-L(Zn)-@Ti 3 C 2 T x (1700 F cm À 3 ), [31] Ti 3 C 2 T x /CAC (1244.6 F cm À 3 ), [37] LC pure Ti 3 C 2 T x (1265 F cm À 3 ), [40] Ti 3 C 2 T x /rGO (341 F cm À 3 ), [48] Ti 3 C 2 T x /CNT (22.7 F cm À 3 ), [49] Ti 3 C 2 T x /Aramid (807 F cm À 3 ), [50] MnO 2 @Ti 3 C 2 T x /CNT (371.1 F cm À 3 ), [51] Ti 3 C 2 T x /PEDOT : PSS (614.5 F cm À 3 ), [43] Ti 3 C 2 T x /rGO (345 F cm À 3 ), [52] shearing Ti 3 C 2 T x (1661 F cm À 3 ), [32a] O-flat Ti 3 C 2 T x (1360 F cm À 3 ), [53] Ti 3 C 2 T x (950 F cm À 3 ), [54] Ti 3 C 2 T x /CNT yarn (1083 F cm À 3 ) [14] and Ti 3 C 2 T x /GO (586.4 F cm À 3 ). [55] In order to satisfy the demands of practical application, we built solid-state asymmetric FSC.…”
