High-Performance Zinc-Ion Hybrid Supercapacitor from Guilin Sanhua Liquor Lees-Derived Carbon Materials.

Aqueous zinc-ion hybrid supercapacitors (ZHSCs) have attracted considerable attention because they are inexpensive and safe. However, the inadequate energy densities, power densities, and cycling performance of current ZHSC energy-storage devices are impediments that need to be overcome to enable the further development and commercialization of this technology. To address these issues, in this study, we prepared carbon-based ZHSCs using a series of porous carbon materials derived from Sanhua liquor lees (SLPCs).

Enhancing thermal conductivity of polyimide composite film by electrostatic self-assembly and two-step synergism of AlO microspheres and BN nanosheets.

To improve the perfection of a three-dimensional thermally conductive network in polyimide (PI) composite film and with respect to the economy and simplicity of processing, a strategy of the two-step synergism of AlO microspheres and hexagonal boron nitride (BN) nanosheets was proposed. First, BN nanosheet-coated AlO microspheres (AlO@BN) were prepared by electrostatic self-assembly method for the first step of the synergism. Then, the AlO@BN&BN/PI composite film containing AlO@BN and BN was fabricated by a two-step method for the second step of the synergism, and was systematically characterized.

A reduced graphene oxide-borate compound-loaded melamine sponge/silicone rubber composite with ultra-high dielectric constant.

Herein, at first, graphene oxide (GO) was prepared by a modified Hummers' method, compounded with borates and then loaded onto a melamine sponge (MS) skeleton by an impregnation-reduction method to obtain a reduced graphene oxide (rGO)-borate compound (rGB)-loaded MS. Then, MS/rGB/silicone rubber (SR) composites were prepared by a vacuum infusion process. Moreover, the microstructures, electrical conductivity, and dielectric properties of the composites were investigated.
