“…Meanwhile, the d-spacing of MF is 1.09 nm, which is 1.75 times higher than that of M. This occurrence is due to the intercalation of F-127 surfactant between the crystal lattice, which caused the MoS 2 lattice structure to expand. This is also observed by Chen et al [40] as the usage of cetyltrimethylammonium bromide (CTAB) surfactant has successfully expanded the MoS 2 interspacing up to 56%.…”

“…However, for the MoS 2 /NC heteroaerogel, the two peaks shift to 378.1 and 400.2 cm −1 , respectively. The blue shift of E 1 2 g peak and the red shift of A 1 g peak are particular signals induced by the carbon insertion 40 , 41 . Besides, the other two peaks centered at ~1350.1 and ~1590.9 cm −1 corresponding to the typical D and G bands of graphitized carbons are also observed.…”

The intercalation strategy has become crucial for 2D layered materials to achieve desirable properties, however, the intercalated guests are often limited to metal ions or small molecules. Here, we develop a simple, mild and efficient polymer-direct-intercalation strategy that different polymers (polyethyleneimine and polyethylene glycol) can directly intercalate into the MoS2 interlayers, forming MoS2-polymer composites and interlayer-expanded MoS2/carbon heteroaerogels after carbonization. The polymer-direct-intercalation behavior has been investigated by substantial characterizations and molecular dynamic calculations. The resulting composite heteroaerogels possess 3D conductive MoS2/C frameworks, expanded MoS2 interlayers (0.98 nm), high MoS2 contents (up to 74%) and high Mo valence (+6), beneficial to fast and stable charge transport and enhanced pseudocapacitive energy storage. Consequently, the typical MoS2/N-doped carbon heteroaerogels exhibit outstanding supercapacitor performance, such as ultrahigh capacitance, remarkable rate capability and excellent cycling stability. This study offers a new intercalation strategy which may be generally applicable to 2D materials for promising energy applications.

“…One way to overcome this problem is to expand the layered MoS 2 but it will lead to a decrease in diffusion energy for ion intercalation. [100,101] Sari et al [91] have coupled MoS 2 with MoO x and the nanostructure was grown upon the activated carbon cloth by the one-step microwave-assisted hydrothermal method. Here, the ACCs played a significant role in enhancing electron transfer, providing good mechanical strength, increasing the electrolyte adsorption.…”

Carbon cloths are the important materials composed of woven carbon fibres having the diameters in the range of 5–10 μm. These materials have been investigated for innumerable applications such as supercapacitors (symmetric and asymmetric), batteries, solar cells, and catalysis. They are found to be the best supports as supercapacitive materials by providing high surface area, conductivity and flexibility compared to much widely used substrate materials such as Ni foam and 1D Fe nanowires. High conductivity and surface area of carbon cloths enable ion diffusion and cause decrease in charge transfer resistance, resulting in an increase of specific capacitance of specific electrodes. Several supercapacitive metal oxides, chalcogenides, phosphides, MXenes, carbon nanotubes, graphene, and conductive polymers have been incorporated into carbon cloths to improve their energy storage activity. Further modification of carbon cloth surface via oxidation, doping and by the growth of different nanostructures is also helpful as it increases the electroactive surface area necessary for electrochemical interaction. The present review mainly focuses on the development of flexible supercapacitors using carbon cloth‐based substrate materials. Such flexible supercapacitors can be further utilized for an uninterrupted and steady power supply to wearable and portable electronic devices.
