New Generation

As a new-generation green composite, core-shell structure nature fibers/ polymer composites (NFPC) has been recently developed and used to enhance performance characteristics of composites. The shell layer, made of thermopolymers unfilled or filled with minerals or nature fibers and other additives, plays a critical role in enhancing overall composite properties. The co-extrusion technology for different structural and material combinations are, however, needed to achieve desired processing. In this paper, co-extrusion technology and core-shell structure NFPC have been discussed by systematically studying the effect of structure on properties of NFPC. The result of this paper can help provide a fundamental base for developing new functional applications of core-shell structure NFPCs.

Core Shell Structure

In order to explore the supercapacitor electrode material with high energy density, a composite material that nickel-cobalt sulfide loaded in graphene (NiCo2S4@rGO) with core-shell structure was successfully prepared by hydrothermal, room temperature vulcanization and annealing. The core-shell structure of the material greatly increased the contact area between the material and the electrolyte and improved the electrochemical performance. In addition, the energy density has been significantly improved. NiCo2S4@rGO was characterized by field emission scanning electron microscopy (SEM), high-resolution transmission electron microscope (HRTEM), X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR) and Raman spectrometer. The electrochemical properties of the material were evaluated by cyclic voltammetry (CV), galvanostatic charge-discharge (GCD) and electrochemical impedance spectroscopy (EIS). The results show that the capacitance can reach 1100 F/g at the current density of 0.5 A/g. Furthermore, the NiCo2S4@rGO as positive electrode and reduced graphene oxide (rGO) as negative electrode were assembled into an asymmetric supercapacitor (ASC). The device exhibits a high energy density of 74.78 Wh/Kg at a power density of 400 W/Kg, as well as excellent cycling stability of 88.9% after 3 000 cycles, which reflects the excellent electrochemical performance of the material.
