“…For example, various green aqueous binders, such as sodium carboxymethylcellulose, pectin, and methylcellulose, were used to synthesize the lithium-ion battery instead of poly(vinylidene fluoride), an organic and toxic binder. To process nanocarbon functional materials in aqueous phase, some chemical modifications − have been employed to introduce polar groups to the nanocarbon materials, improving their hydrophilic property. On the other hand, the physical properties of nanocarbon materials mainly depended on their molecular structure, especially for the conjugated structures between the carbon atoms .…”

Nanocarbon materials (NCM) have been widely applied in electronic and energy industries. With the rise of environmental concerns, nanocarbon material-based electronic and energy devices were prone to be fabricated by the aqueous process. Unfortunately, the low dispersibility of carbon nanomaterials in water and the strong π−π interaction between the carbon nanomaterials limited these processes. This research introduced a kind of metal−phenolic network, tannic acid−Fe 3+ (TA-Fe III ), as a universal aqueous dispersing and immobilizing agent for nanocarbon materials. The nanocarbon material-based electronic and energy materials were synthesized in the aqueous phase. Meanwhile, the TA-Fe III exhibits better-dispersing properties than TA because of its larger contact area with nanocarbon materials. The steered molecular dynamics simulation results also supported this point. They revealed that some arms of TA-Fe III could tightly attach to the surface of the NCM by π−π stacking interaction. To explore the potential application of NCM/TA-Fe III dispersion, we tried to synthesis of electronic and energy materials in the aqueous phase. The reduced graphene oxide (RGO)/TA-Fe III dispersion was used to fabricate anode materials of lithium batteries, which exhibit higher specific capacity than the cells that employed RGO or RGO/TA as anode materials. Moreover, the multiwalled carbon nanotube/TA-Fe III dispersion could self-assemble into a coating on chitosan hydrogel to improve its conductivity. The coated chitosan hydrogel exhibited sensitive electromechanical performance under cyclic compression−release. Hence, the metal−phenolic network/NCM dispersion can be used to fabricate wearable electronics and power storage devices in the aqueous phase.
