Supermolecular complexation with cyclodextrins by non-covalent host-guest interaction is used for various applications. In this work, we fabricated the freestanding and flexible core-shell MnO/carbon nanofiber (CNF) composite thin films by host-guest interaction and high-voltage electrospining technique. The as-prepared composite thin film with dual carbon layer nanofibers showed smaller MnO particle...
Red phosphorus (P) shows enormous potential as a high-performance and cost-effective Lithium (Li)-ion anode material. It alloys with Li forming Li3P, which translates to a theoretical capacity of ∼2595 mAh g−1 (∼7 times better than graphite). Further, the cost of bulk P is comparable to battery-grade graphite. However, there are two intrinsic limitations that prevent deployment of P, viz., its low...
Graphene has an ultra-high thermal conductivity (TC) along its basin plane. However, the TC of graphene/metal composites is still far below the expectation due primarily to the lack of sufficient graphene alignment in the metal matrix. Herein, we reported an efficient route to prepare the graphene nanoplatelet (GNP)/Cu composites with highly aligned GNPs by a vacuum filtration method followed by spark...
Three-dimensional (3D) porous graphene materials with few layer nature and non-stacked structural feature afford significant advantages in high electrical conductivity, large surface area, and interconnected porous nanostructures. However, the structure evolution of porous graphene under high temperature is poorly understood. In this contribution, 3D double-layer templated graphene (DTG) composed...
