Thin Copper Foils: From Electrodeposition Conditions to Adhesion Performances Ivana O. Mladenović, Željko Radovanović, Dana G. Vasiljević-Radović, Rastko Vasilić, Miloš Vorkapić, et al. Materials, 2026 Cathodic electrodeposition of copper on molybdenum and stainless-steel substrates has been investigated with the aim of examining their potential to produce thin copper foils (TCFs). Copper in the form of a thin film was electrodeposited galvanostatically from the acidic sulfate electrolyte without and with an addition of suppressor/activator additives, such as chloride ions, polyethylene glycol 6000 and 3–mercapto–1–propanesulfonic acid. The cathodes and electrodeposited Cu films were characterized by SEM, AFM, and XRD techniques, while the adhesion of Cu films, as a crucial parameter in the production of Cu foils, was estimated by a lab-made prototype of a bending test machine made by applying additive technology. The adhesion parameter named “critical cycle number” (nc), which defines the minimal number of cycles leading to a delamination (separation) of the film from the cathode was used for assessing the adhesion features of the films. The easiest delamination, i.e., the smallest nc, showed nanocrystalline films obtained with the addition of all additives, whereupon the values were significantly smaller than the values obtained for microcrystalline films obtained without and with a partial combination of the additives. The easy delamination of the nanocrystalline films indicated that both substrates have a high potential for application in the production of TCFs.
Tailoring Mechanical and Surface Properties of Epoxy Coatings with Synthesized Pigment Particles: Microhardness, Adhesion, and Wettability Studies Nikola Nedeljković, Ivana O. Mladenović, Marija M. Vuksanović, Jelena Lamovec, Milica Ž. Mušicki Bogdanović, et al. Coatings, 2026 Epoxy resins are widely used in coatings and adhesives due to their strong adhesion and processability. In this study, epoxy-based coatings were prepared with two synthesized pigments: cobalt blue and chrome orange. The coatings were applied to aluminum, phosphor bronze, and brass substrates to evaluate mechanical and adhesive performance. Microhardness was analyzed using the Chen–Gao model to exclude substrate effects, while adhesion was assessed via parameter b. Pigment morphology strongly influenced the properties: Pb-orange exhibited hollow micro-tube structures, while Co-blue showed an irregular morphology. Results revealed that epoxy coatings on brass with Pb-orange pigment reached a hardness of 242.6 MPa, compared to 187.2 MPa for Co-blue, representing a 22.8% increase. Adhesion was superior in epoxy/Pb-orange, with values 1.3 times higher than epoxy/Co-blue and 1.8 times higher than neat epoxy on brass. However, pigments have no influence on the intrinsic hardness of the epoxy coating. The orange pigment in the epoxy impairs wetting resistance, while the blue pigmented epoxy coating becomes hydrophobic. In this way, in addition to colorizing epoxy coatings, multifunctional coatings with adjustable adhesion, free surface energy, and hardness are also obtained. These findings highlight the potential of pigment-modified coatings for tailored industrial applications, offering improved properties depending on pigment selection.
The Comprehensive Study of TiO2 Blocking Layer with Complementary Electrochemical and SPM Methods for the Application in Photovoltaics Evgenija Milinković, Katarina Cvetanović, Marko V. Bošković, Nastasija Conić, Vladislav Jovanov, et al. Inorganics, 2025 The blocking layer is crucial for inhibiting recombination processes in photovoltaics that utilize oxide semiconductors, such as dye-sensitized solar cells (DSSCs), quantum-dot-sensitized solar cells (QDSSCs), and perovskite solar cells. However, its effectiveness strongly depends on the chosen deposition method. This study systematically evaluates the most suitable approach for obtaining a uniform, pinhole-free titanium dioxide (TiO2) blocking layer by using three deposition methods: radio-frequency sputtering, spin-coating, and chemical bath deposition. The electrochemical, optical, and morphological properties of blocking layers were characterized using cyclic voltammetry (CV), electrochemical impedance spectroscopy (EIS), UV-VIS spectroscopy, scanning electron microscopy (SEM), atomic force microscopy (AFM), and Kelvin probe force microscopy (KPFM). KPFM analysis, together with CV and EIS, revealed that the lower Rct values and higher CV currents observed in spin-coated (SC_11-33) and vertically deposited CBD films (CB_5, CB_6) resulted from incomplete FTO coverage. In contrast, sputtered (SP_21-24) and horizontally deposited CBD films (CB_1, CB_2) demonstrated significantly higher Rct values and improved surface coverage. Full DSSCs fabricated with SP_23, SC_33, and CB_2 confirmed the correlation between interfacial properties and photovoltaic performance. This combined approach offers a fast, material-efficient, and environmentally conscious screening method for optimizing blocking layers in solar cell technologies.
Evaluation of Adhesion Properties of Electrodeposited Copper Thin Films: Theoretical and Experimental Approach Ivana O. Mladenović, Jelena S. Lamovec, Dana G. Vasiljević-Radović, Rastko Vasilić, Vesna J. Radojević, et al. Materials, 2025 The adhesion of copper thin films galvanostatically electrodeposited on Cu cathodes from electrolytes without or with the addition of various additives, such as chloride ions, polyethylene glycol 6000 (PEG 6000), and 3–mercapto–1–propanesulfonic acid, has been investigated. Morphological and structural analyses of synthesized films were performed using the SEM, AFM, and XRD methods, while the adhesion of the films was examined by applying the theoretical Chen–Gao (C–G) composite hardness model using results from Vickers microindentation, a bidirectional bending test, and a scratch-tape adhesion test. The morphologies of the films were either very smooth, with mirror-like brightness, obtained from the electrolyte containing all three additives, or microcrystalline, with different grain sizes, obtained from other electrolytes. The best adhesion was observed in the fine-grained film with numerous boundaries among grains, obtained with the addition of chloride ions and PEG 6000, while the mirror-bright film obtained with a combination of all three additives showed the worst adhesion. The boundaries among grains represented barriers that decreased the depth of penetration during microindentation and, consequently, increased the hardness and enhanced the adhesion of the film. The size of the grains—and hence, the number of grain boundaries—was regulated by the composition of the electrolytes achieved by the addition of additives. Good agreement was observed among the various methods used for the estimation of the adhesion properties of Cu films.
Insight into the Oxygen-Sensing Mechanisms of TiO2–CeO2 Mixed Oxides Treated in a High-Energy Ball Mill: An XPS Analysis Jelena N. Stevanović, Ana G. Silva, Nenad Bundaleski, Dana Vasiljević-Radović, Milija Sarajlić, et al. Inorganics, 2025 This study explored the oxygen-sensing mechanism of CeO2 modified with TiO2 via high-energy ball milling at different speeds. Different characterization techniques were employed to investigate the obtained materials. Quantitative surface analysis by X-ray photoelectron spectroscopy was conducted to elucidate their sensitivity mechanisms and assess the impact of the introduction of TiO2. A comparable concentration of oxygen vacancies was found in the samples milled at 350 and 450 rpm. Electrical measurements conducted at temperatures lower than required for semiconductor gas sensors revealed the higher sensitivity of these two samples in comparison to pure CeO2 at an oxygen concentration above 10%. In contrast, the samples derived from precursors milled at the highest speed exhibited the lowest sensitivity. This may be linked to a slight decrease in the vacancy concentration and the presence of a differentially charged carbon-containing phase. Eventually, the C 1s line provided significant insight into the surface characteristics of the materials. The uniform and non-uniform charging found for pure TiO2 and CeO2, respectively, along with the high charging of CeO2, suggest that TiO2 promotes the contact between the sensing layer and the overlayer. Sensor testing showed the significantly lower resistance of mixed oxides in comparison to CeO2, which increases the utility of metal oxide-based sensors.
