Delaminated Ti 3 C 2 T x (D-Ti 3 C 2 T x ) MXene films exhibit excellent electrochemical and electromagnetic interference (EMI) shielding performance. However, the low yield and easy oxidation of D-Ti 3 C 2 T x nanosheet limit its commercial application. Herein, the flexible green multilayered Ti 3 C 2 T x /hydroxyethyl cellulose (M-Ti 3 C 2 T x /HEC) composite film was successfully fabricated through...
To explore the effect of tube sizes and filling process on dielectric properties of carbon nanotubes (CNTs), CNTs with various diameters and lengths were applied to synthesize Fe-filled CNTs through wet-chemical method. The permittivities of the composites of CNTs and paraffin rely on the dispersion state (agglomeration) of CNTs in polymer matrices. During the filling process, CNTs with diverse tube...
Two kinds of surface-enhanced Raman scattering (SERS) substrates structured with hybrid of Ag nanoparticles (AgNPs) and graphene (GE) were synthesized, namely GE underneath AgNPs (AgNPs-GE) and GE covered AgNPs (GE-AgNPs). They provide a platform to make a comparative study on the optical properties and SERS effects of the hybrid structures as well as on the interactions between AgNPs and GE. The...
A three-dimensional (3D) surface-enhanced Raman scattering (SERS) substrate is fabricated by decorating multi-walled carbon nanotubes (MWNTs) arrays with silver nanoparticles (AgNPs) on silicon, via magnetron sputtering and annealing method. The MWNTs-AgNPs hybrids with 3D structure increase the coverage of plasmonic nanostructures. The effect of inter-particle and inter-tube coupling creates a multitude...
We synthesized a set of surface-enhanced Raman scattering (SERS) substrates with hybrid-structures including Ag nanoparticles (AgNPs), AgNPs on top of few-layer graphene (AgNPs-FLG), AgNPs underneath few-layer graphene (FLG-AgNPs), sandwich structure (FLG-AgNPs-FLG) and few-layer graphene (FLG). The experimental results indicate that FLG can effectively protect AgNPs against aerobic oxidation (up...
Carbon nanotube (CNT) based continuous fiber, a CNT assembly that could retain the superb properties of individual CNTs on a macroscopic scale, has emerged as a promising candidate for reinforcement in multifunctional composites. While existing research has extensively examined their short-term mechanical properties based upon quasi-static measurements, the long-term durability of CNT fibers has been...
Hollow carbon nanospheres (HCNSs) were prepared on large scale by the reaction of AlCl 3 ·6H 2 O and CaC 2 in the temperature range of 250–500°C. Characterization of the products by X-ray diffraction, Raman spectroscopy and transmission electron microscopy indicates that they have a uniform size of about 30nm and a high degree of graphitization. Based on a series of comparative...
