In recent years, Chemical Vapor Deposition (CVD) has emerged as a pivotal technique for the synthesis of high-quality nanomaterials, owing to its ability to produce uniform and scalable thin films with controlled properties. This study presents a comprehensive characterization and modelling of nanomaterials synthesized via CVD, elucidating the intricate relationship between process parameters and the resultant material properties. Utilizing advanced characterization techniques, including Transmission Electron Microscopy (TEM), XPS, and Raman Spectroscopy, we have discerned the morphological, compositional, and structural attributes of the synthesized nanomaterials. The experimental data were subsequently employed to develop a predictive model, leveraging machine learning algorithms, to forecast the properties of nanomaterials based on CVD parameters. The model exhibited high accuracy and can serve as a robust tool for optimizing CVD processes in real-time. Our findings underscore the potential of CVD in tailoring nanomaterial properties for specific applications and provide a foundational framework for researchers and industries aiming to harness the full potential of nanomaterials synthesized via CVD. This work not only advances our understanding of CVD-synthesized nanomaterials but also paves the way for their application in next-generation electronic, photonic, and energy devices.

Based on the epoxidation modification of the carbon nanotubes surface, we develop a facile one‐pot synthesis of core‐shell magnetic carbon nanotubes where Fe3O4 nanoparticles are encapsulated inside the carbon nanotubes (Fe3O4@CNTs). Compared with traditional magnetic carbon nanotubes which prepared by surface deposition, the well‐designed core‐shell magnetic carbon nanotubes show higher selective adsorption for aromatic organic compounds. For those aromatic compounds containing hydrophilic groups on benzene rings such as phenols, the equilibrium adsorption capacity of the compound on the surface of Fe3O4@CNTs is almost zero. Conversely, the Fe3O4@CNTs exhibit good adsorption capacity for those aromatic compounds with electron‐withdrawing group on benzene ring such as nitro group, and the equilibrium adsorption capacity can reach 2.07 mg/g in aqueous solution. In addition, the corresponding selective adsorption mechanism is put forward through the kinetic studies. This study provides a new strategy for the water environmental treatment and the reuse of aromatic pollutants.

Marine biofouling had been a headache when engaging in marine activities. The most effective and convenient method for dealing with this problem was to apply antifouling coatings. But now a single anti‐fouling system was hard to satisfy the requirement of anti‐fouling simultaneously. Therefore, it was particularly important to develop novel multi‐system anti‐fouling technology. In the work, a novel polymer coatings with polydimethylsiloxane (PDMS) segments in the main chain and hydrolysable side chain was designed and synthesized which showed low surface energy and self‐polishing performance, and then we creatively covalently immobilized the polyurethane on the surface of multi‐carbon nanotubes (MWNTs) to form multisystem antifouling coating. The results showed that the polymer coating would produce hydrolysable regions in the hydrophobic PDMS segment to endure the polymer coating hydrophobic and hydrolysis properties when contacted with water. In addition, the self‐polishing rate and the surface energy could be regulated by varying its copolymerization, and the addition of MWNTs could kill the microorganisms and endowed the polymer coating itself enhanced antibacterial effect. Furthermore, considering the high specific surface area and physicochemical characteristics of MWNTs, it could be combined with antifoulant Cu2O through a polar or non‐polar combination as a carrier to control the release rate of Cu2O in coatings.
