摘要
Nanoscale materials can have outstanding properties, but it can be challenging to assemble them into larger fibers or sheets while retaining their intrinsic capabilities. For example, MXene nanosheets have excellent mechanical and electrical properties that are promising for flexible electronic devices and aerospace applications. Li et al. fabricated MXene films at room temperature using bacterial cellulose and liquid metal to sequentially bridge the nanosheets. The orientation of the MXene nanosheets was dramatically improved by the blade-coating layer-by-layer process, and the liquid metal effectively filled any voids. The interfacial interactions between sheets were also improved by hydrogen bonding from the bacterial cellulose and coordination bonding with the liquid metal, enhancing the stress transfer efficiency. —Marc S.
