“…Again, from Guo et al, , the pulse-modulated DLC deposition from various organic solvents showed the broadened D and G band under low dc bias conditions of DLC patterns, which may attribute to the small granular carbon deposits as well as the high amount of hydrogen content. The decreasing trends in the intensity ratio of the D band to the G band, i.e., I D / I G were found to be 1.14, 1.10, and 0.66 in DLC 0.5 , DLC 1.0 , and DLC 1.5 , respectively, were attributed to the increasing order in the sp 3 content in the DLC patterns. ,,, The lowest I D / I G in the DLC 1.5 patterned film indicates a high sp 3 –sp 2 ratio in the DLC film as compared to DLC 0.5 and DLC 1.0 .…”

“…Diamond-like carbon (DLC) is well known to outperform amorphous carbon material composed of the sp 3 - and sp 2 -hybridized carbon phase along with hydrogen atoms. , It is well known for low friction, high wear resistance, high thermal stability, chemical inertness, and high electrical resistivity due to the presence of higher sp 3 (diamond phase) in the amorphous carbon matrix. , Its intriguing properties such as high Young’s modulus, wide bandgap, high carrier mobility, low thermal expansion coefficient, and biocompatibility nature of the DLC materials give a unique platform for various technological advancements. Due to its robustness in material properties, it has been applied in a wide range of technological applications such as microelectromechanical systems, protective coatings, field emission, field-effect transistor, and bio-applications. − …”

Diamond-like Carbon Patterning by the Submerged Discharge Plasma Technique via Soft Solution Processing

Submerged plasma-assisted discharge direct patterning of diamond-like carbon (DLC) onto the silicon substrate in ambient conditions has succeeded as a new and novel soft solution process. In this environmentally benign technique, a copious amount of pure ethanol (ca. 4 mL) was locally activated with a maximum of ca. 0.23 mkWh by an aselectrochemically synthesized ultrasharp tungsten tip. With the assisted submerged plasma, the decomposed ethanol molecules are anodically patterned directly onto the silicon substrate in ambient conditions. The physical nature of DLC patterns was accessed by profilometry, atomic force microscopy, scanning electron microscopy, and transmission electron microscopy analysis. Furthermore, Fourier-transform infrared, Raman, and X-ray photoelectron spectra were analyzed for chemical compositions and structures, such as surface functionalization, carbon−carbon bonding, and sp 2 −sp 3 ratio, respectively. From a Berkovich-configured nanoindentation analysis, Young's modulus and hardness have shown increasing trend with increasing sp 3 −sp 2 ratio in DLC patterns of 68.5 and 2.8 GPa, respectively. From the electrochemical cyclovoltammetry analysis, a maximum areal specific capacitance of 205.5 μF/cm 2 has been achieved at a scan rate of 5 mV/s. The one-step, green, and environmentally sustainable approach of rapid formation of DLC patterns is thus a promising technique for various carbon-based electrode fabrication processes.

Effect of Poly Dimethyl Diallyl Ammonium Chloride‐Multiwalled Carbon Nanotubes Concentration on the Microstructure and Friction Behavior of Co‐Doped Diamond‐Like Carbon Films

et al. 2023

A kind of wear-resistant diamond-like carbon (DLC) films doped with Ni, N, and multiwalled carbon nanotubes (MWCNTs) are synthesized on Ti-6Al-4V titanium alloy by a combined method of pulsed electrodeposition and liquid-phase electrodeposition. The effect of different concentrations of MWCNTs on the microstructure and friction mechanism of Co-DLC films is investigated. The results show that the polydimethyl diallyl ammonium chloride (PDDA)-MWCNTs complex tend to deposit parallel to the substrate. Benefiting from the "bridging" effect of the MWCNTs between the cluster structures, it effectively reduces the protrusions on the surface of the films. When the concentration of MWCNTs is 0.06 g L À1 , the surface microstructure of the films is uniform and dense, and the films present a low I D /I G value (0.57) and a high sp 3 -C content. The Raman and X-ray photoelectron spectroscopy patterns reveal that the Ni/N/MWCNTs-DLC films are typical amorphous carbon films. Furthermore, the micro-indentation hardness of the Co-DLC films reaches 513.24 HV. The lubricated Ni/N/MWCNTs-DLC films significantly improve the frictional wear properties of the titanium alloy surface, which is mainly attributed to the homogeneous and dense structure and the low friction coefficient (0.146) and wear loss (1.40 Â 10 À5 kg m À1 ).
