纳米碳材料（NCM）已广泛应用于电子和能源行业。随着环境问题的兴起，基于纳米碳材料的电子和能源设备倾向于通过水相工艺制造。不幸的是，碳纳米材料在水中的低分散性以及碳纳米材料之间强的π-π相互作用限制了这些过程。本研究介绍了一种金属-酚网络，单宁酸-Fe3+(TA-FeIII)，作为纳米碳材料的通用水分散剂和固定剂。在水相中合成了基于纳米碳材料的电子和能源材料。同时，TA-FeIII由于与纳米碳材料的接触面积更大，因此表现出比TA更好的分散性能。导向分子动力学模拟结果也支持了这一点。他们发现，TA-FeIII 的一些臂可以通过 π-π 堆积相互作用紧密附着在 NCM 表面。为了探索NCM/TA-FeIII分散体的潜在应用，我们尝试在水相中合成电子和能源材料。还原氧化石墨烯（RGO）/TA-FeIII分散体用于制造锂电池负极材料，其比采用RGO或RGO/TA作为负极材料的电池表现出更高的比容量。此外，多壁碳纳米管/TA-FeIII分散体可以自组装成壳聚糖水凝胶上的涂层，以提高其电导率。涂层壳聚糖水凝胶在循环压缩-释放下表现出敏感的机电性能。因此，金属-酚醛网络/NCM分散体可用于在水相中制造可穿戴电子设备和电力存储设备。
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–Fe3+(TA-FeIII), 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-FeIIIexhibits 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-FeIIIcould tightly attach to the surface of the NCM by π–π stacking interaction. To explore the potential application of NCM/TA-FeIIIdispersion, we tried to synthesis of electronic and energy materials in the aqueous phase. The reduced graphene oxide (RGO)/TA-FeIIIdispersion 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-FeIIIdispersion 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.
