“…Diamond‐like carbon (DLC) films are being developed for a wide range of applications in fabricating mechanical, acoustic, electronic, and optical devices, and magnetic media protection coatings . Usually, DLC films are in heterogeneous metastable form of carbon with a mixture of graphite‐like sp 2 and diamond‐like sp 3 hybridized bonding .…”

“…Therefore, the properties of DLC films are determined not only by the relative fraction of sp 2 /sp 3 ‐hybridized bonds but also by the organization of the bonding network for carbon atoms (cluster size, ordering degree, atomic rearrangement, etc.). Disappointingly, however, the practical applications of DLC films are still restricted by the low adhesion to substrate resulting from high residual internal stress . An effective approach for solving the adherence problem is producing functional films in the form of interlayer between the substrate and the DLC films.…”

Titanium/diamond‐like carbon (Ti/DLC) bilayer films with different relative thickness were fabricated by direct‐current and pulsed cathode arc plasma method. Microstructure, morphological characteristics, and mechanical properties of the films were investigated in dependence of the thickness of Ti and DLC layers by Raman spectroscopy, atomic force microscopy, Knoop sclerometer, and surface profilometer. Raman spectra of Ti/DLC bilayers show the microstructure evolution (the size and ordering degree of sp2‐hybridized carbon clusters) with varying the thicknesses of Ti interlayer and DLC layer. Nano‐scaled Ti interlayer of 12–20 nm thickness presents the largest size effect. The catalytic effect of the sublayer is most pronounced in the carbon layer of less than 106 nm. In these thickness ranges, the bilayer films possessed the highest micro‐hardness and reactivity between atoms at interface. Internal stress in the bilayer monotonically decreases, with the thickness of Ti interlayer increasing to 30 nm and then becomes stable with the thickness. These results are associated with the occurrence of atomic diffusion process at Ti/C interface, and they are of cardinal significance to optimize the structure and mechanical properties of carbon‐based multilayer films.

“…Therefore the position of the G peak shifts to a lower wave-number in the DLC film by PLA, indicating more disordered Csp 2 clusters present in the films. This may be related to the high ions energy density during PLA, facilitating the formation of sp 3 hybridized bonding [17,18]. Fig.…”

“…DLC films are widely applied as protective coatings, such as mechanical, acoustic, electronic and optical devices and magnetic media because of their excellent properties, including high mechanical hardness, optical transparency, good chemical stability and thermal conductivity [1][2][3].

Abstract. Diamond-like carbon (DLC) films were prepared on silicon substrate using four different vacuum plasma methods: magnetron sputtering (MS), pulse laser ablation (PLA), ion beam deposition (IBD) and pulse cathode vacuum arc evaporation (CVAE). The microstructure, surface morphology and optical properties of the DLC films were investigated by Raman spectroscopy, atomic force microscope (AFM) and UV-visible spectrophotometer. The results showed that the films prepared by different vacuum plasma methods varied in the microstructure. The film prepared by CVAE possessed the smallest grain size of graphite with the highest disordering of Csp2 clusters, while more disordered Csp2 clusters presented in the DLC film due to the high ions energy density during PLA. Meanwhile, the deposition methods mainly affected the size of particles and roughness of the DLC films under the same thickness. The film by PLA shows a quite smooth surface structure with uniform particle size. In terms of the optical properties, the films prepared by magnetron sputtering expressed the best optical performance among the four vacuum plasma methods.

Weaker Interactions in Zn²⁺ and Organic Ion‐pre‐intercalated Vanadium Oxide toward Highly Reversible Zinc‐ion Batteries

Driven by safety issues, environmental concerns, and high costs, rechargeable aqueous zinc‐ion batteries (ZIBs) have received increasing attention in recent years owing to their unique advantages. However, the sluggish kinetics of divalent charge Zn2+ in the cathode materials caused by the strong electrostatic interaction and their unsatisfactory cycle life hinder the development of ZIBs. Herein, organic cations and Zn2+ ions co‐pre‐inserted vanadium oxide ([N(CH3)4]0.77,Zn0.23)V8O20·3.8H2O are reported as the cathode for ultra‐stable aqueous ZIBs, in which the weaker electrostatic interactions between Zn2+ and organic ion‐pinned vanadium oxide can induce the high reversibility of Zn2+ insertion and extraction, thereby improving the cycle life. It is demonstrated that ([N(CH3)4]0.77,Zn0.23)V8O20·3.8H2O cathodes deliver a discharge capacity of 181 mA h g−1 at 8 A g−1 and ultra‐long life span (99.5% capacity retention after 2000 cycles). A reversible Zn2+/H+ ions (de)intercalation storage process and pseudocapacitive charge storage are characterized. The weaker interactions between organic ion and Zn2+ open a novel avenue for the design of highly reversible cathode materials with long‐term cycling stability.
