Summary: This study investigated the use of PEALD to develop a Zn-Al composite oxide-based antibacterial moisture barrier film for flexible electronic devices. The transmittance, refractive index, water vapor transmission rate (WVTR), antibacterial and antifungal properties of the Zn-Al composite oxide films were evaluated. The results showed that the films with higher Zn ratio had higher refractive index and lower transmittance, and the film with a Zn ratio of 10.4 demonstrated the best WVTR. All samples exhibited high antibacterial activities and no mould growth.

Summary: In this study, a thin-film based 4-layered anode-supported solid oxide fuel cell with a large-area was fabricated. The cell showed a high-power output of 41.5W at 50A and a maximum power density of 1.6 Wcm-2 at 700 degrees C. Long-term testing demonstrated a degradation rate of 0.2% kh-1 at 25A current, meeting the stringent benchmark for commercialization.

Summary: By combining oblique angle deposition and atmospheric pressure plasma jet, we have successfully produced GZO films with uniform ultrahigh haze, high transmittance, and low resistivity. Unlike conventional methods, our single-step approach does not require additional steps/materials or parameter changes during operation.

Summary: Transparent films with symmetric sandwich structure were designed using layer-by-layer assembly of biaxially oriented polypropylene (BOPP) and acrylic resin (AR) with a cellulose nanoparticle (CNP) layer. The aspect ratio of CNPs affected film microstructure, resulting in different oxygen transmission rates (OTR). Well-organized CNP layer exhibited lower OTR compared to network layer, with thickness, density, and porosity of CNP layer correlating with OTR. Water vapor transmission rate (WVTR) increased due to additional water pathway, while these cellulose composite films showed excellent light transmittance and tensile strength.

Summary: This paper focuses on the solution to the chemical instability and decomposition issues of pure Ag nanowire-based thin films during thermal processes by using MoOx/Ag nanowire bilayers. Under optimal conditions, the bilayer thin films exhibit low sheet resistance and high optical transmittance, along with excellent thermal stability and adhesion. Moreover, they retain their conductivity even under harsh corrosion environments. The bilayer thin films are also applied to fabricate a transparent heater with efficient heating, deicing, and defogging capabilities.

Summary: This study successfully fabricated fully-transparent and highly-conductive Al-doped ZnO films using the atomic layer deposition method. The influence of Al doping on the film properties and current conduction mechanisms was analyzed, and it was found that Al doping improves electron concentration and optical bandgap width, resulting in excellent combination of low resistivity and high transmittance. Furthermore, Al doping improves surface properties and enhances current conduction. Transparent ZnO thin film transistors with superior transparency and performance were successfully fabricated.

Summary: In this study, a coating-annealing approach was utilized to fabricate highly transparent, hydrophobic, and durable anisotropic cellulose films. Low surface energy chemicals poly(methyl methacrylate)-b-poly(trifluoroethyl methacrylate) (PMMA-b-PTFEMA) were coated onto regenerated cellulose films through physical and chemical interactions. The resulting films exhibited nano-protrusions, low surface roughness, high optical transparency, good hydrophobicity, and excellent stability and durability under various conditions. This work provides a promising large-scale production strategy for transparent and hydrophobic cellulose-based films for electronic device protection and other emerging flexible electronics.
