In this study, biomass-derived carbon has recently gained significant attention due to its sustainability and potential for large-scale production. However, achieving both lightweight properties and strong, broadband absorption performance remains a challenge. To address these challenges, we employed a simple hydrothermal synthesis method to deposit magnetic particles onto the surfaces of biomass-derived carbon, thereby producing C/CoNi composites with excellent electromagnetic wave absorption (EWA) characteristics. The uniform dispersion of magnetic particles on the biomass carbon surface enhances the interfacial polarization effect, while the introduction of CoNi significantly enhances the surface conductivity of the C/CoNi composites, thereby improving their microwave absorption performance. Consequently, these composites demonstrate outstanding EWA properties, characterized by thin-layer structures, lightweight design, wide frequency bandwidth, and high absorption efficiency. When combined with paraffin wax (30 wt% loading), the composite exhibits a minimum reflection loss (RL<sub>min</sub>) of −54.59 dB and an effective absorption bandwidth (EAB) of 3.96 GHz.

However, their poor adhesion to substrates remains a significant challenge. While high compressive residual stress in the film is widely believed to weaken adhesion, the primary factors governing delamination initiation are still not well understood. In this study, we performed molecular dynamics simulations to investigate the key factors affecting the delamination strength and to clarify the underlying mechanisms. First, the deposition process of the DLC film was simulated on Fe-BCC and C-diamond substrates to prepare the DLC-coated substrate systems. Then, for these DLC-coated substrate systems, the adhesion strength was quantified according to the separation energy needed to create free surfaces at the interface. Additionally, tensile simulations were conducted to analyze the detachment behavior of the DLC-coated substrate system. The simulation results revealed that as the average compressive residual stress in the film increased, the separation energy at the film–substrate interface decreased linearly. Moreover, the separation energy, which was computed at various position from the film–substrate interface, exhibited a minimum value just above the interface due to the presence of porosity. Tensile simulations confirmed that delamination initiated at the lowest-separation energy regions, occurring earlier on Fe-BCC substrates compared with C-diamond substrates. Residual compressive stress facilitates delamination by reducing the overall separation energy, as the atomic bonds expand normal to the interface owing to Poisson's lateral strain. These findings clarify the effects of the substrate materials and deposition conditions on DLC-film adhesion and provide guidelines for increasing adhesion strength.</div></div>","PeriodicalId":11266,"journal":{"name":"Diamond and Related Materials","volume":"155 ","pages":"Article 112350"},"PeriodicalIF":4.3,"publicationDate":"2025-04-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143848566","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The supercell structure consists of the carbon metal catalyst system enclosed within a graphite heater surrounded by a thermal and electrical insulators. The pressure transmission to the pyrophyllite block which forms the outer envelope of the supercell is essential to ensure the pressure buildup inside the system. The understanding of this pressure transfer, however, is affected by the inability of using traditional monitoring methods due to extreme operating conditions. This requires use of Finite Element Method in order to gain in-depth understanding of the pressure transfer mechanism. In this work a novel finite element framework is used to analyze the pressure generation at the anvil pyrophyllite interface system and pressure transfer through the pyrophyllite. Modelling of Pyrophyllite requires use of Lagrangian elements which distort at high pressure conditions due to its elasto-plastic behavior. To overcome excessive element distortion, local re-meshing needs to be done which not only increases the computational effort but also leads to inaccurate results. This work proposes to use the Coupled Eulerian Lagrangian (CEL) technique to model anvil system where pyrophyllite is modelled using Eulerian elements and anvil is modelled using Lagrangian elements. This solves the issue of mesh distortion as Eulerian elements are fixed in space. Mohr-Columb criteria is used to capture the elasto-plastic behavior of the pyrophyllite.
