Abstract
This study examines the influence of different substrate materials on the structural, mechanical, and hydrophobic properties of diamond-like carbon (DLC) films deposited using the PECVD technique. Substrates including stainless steel, silicon, Silica, and epoxy chip material were investigated to understand their impact on the performance of DLC coatings. Raman, FTIR spectroscopy and XPS revealed substrate-dependent variations in bonding configurations, with stainless steel exhibiting prominent sp2 clustering and graphitization, while Silica displayed a predominantly amorphous structure with enhanced sp3 content. Silicon demonstrated superior mechanical properties, attributed to its hexagonal DLC morphology and higher sp3 bonding, making it ideal for demanding applications. Epoxy chip material, characterized by a globular DLC structure and higher sp2 content, exhibited lower mechanical performance but moderate hydrophobicity. Silica was identified as the most hydrophobic substrate, followed by silicon, epoxy chip, and stainless steel. These findings underscore the importance of substrate characteristics and structural tailoring in optimizing DLC coatings for diverse industrial applications, including protective, tribological, and water-repellent surfaces.
期刊介绍：
The objective of the Journal of Nanoparticle Research is to disseminate knowledge of the physical, chemical and biological phenomena and processes in structures that have at least one lengthscale ranging from molecular to approximately 100 nm (or submicron in some situations), and exhibit improved and novel properties that are a direct result of their small size.
Nanoparticle research is a key component of nanoscience, nanoengineering and nanotechnology.
The focus of the Journal is on the specific concepts, properties, phenomena, and processes related to particles, tubes, layers, macromolecules, clusters and other finite structures of the nanoscale size range. Synthesis, assembly, transport, reactivity, and stability of such structures are considered. Development of in-situ and ex-situ instrumentation for characterization of nanoparticles and their interfaces should be based on new principles for probing properties and phenomena not well understood at the nanometer scale. Modeling and simulation may include atom-based quantum mechanics; molecular dynamics; single-particle, multi-body and continuum based models; fractals; other methods suitable for modeling particle synthesis, assembling and interaction processes. Realization and application of systems, structures and devices with novel functions obtained via precursor nanoparticles is emphasized. Approaches may include gas-, liquid-, solid-, and vacuum-based processes, size reduction, chemical- and bio-self assembly. Contributions include utilization of nanoparticle systems for enhancing a phenomenon or process and particle assembling into hierarchical structures, as well as formulation and the administration of drugs. Synergistic approaches originating from different disciplines and technologies, and interaction between the research providers and users in this field, are encouraged.
