Summary: This paper investigates the application of nano SiO2 particle-modified organic silane coatings on deep-sea optical windows. The results indicate that adding an appropriate amount of nano SiO2 particles can enhance the hydrophobicity, hardness, and adhesion of the coating, while maintaining good transparency. However, excessive addition leads to performance degradation. The optimal coating is obtained by adding 0.5 wt% nano SiO2 particles, which exhibits excellent water scouring resistance and microorganism attachment rate.

Summary: In this study, AlSi nanocomposite coating was deposited on float glass substrate by RF magnetron sputtering in Ar/N2 reactive atmosphere. The effect of deposition time on microstructure, mechanical and optical properties was investigated. The XRD analysis revealed the formation of h-AlN phase in the film deposited for 2 h, indicating a transition from amorphous to polycrystalline structure. The coating thickness increased with deposition time, as confirmed by stylus profiler. The coating exhibited high optical transparency (>90%) and low surface roughness (Ra < 2 nm). The maximum hardness of the coating was 31 GPa with an elastic recovery of 92%.

Summary: In recent years, the application of highly transparent hydrophobic coatings has been a focus in preventing smudging on electronic displays, automotive glass surfaces, and solar cell surfaces. This study developed a novel hydrophobic melamine resin by modifying melamine with stearyl chloride, leading to the fabrication of high-transparency hydrophobic coatings. The incorporation of long-chain alkyl materials and polyethylene glycol improved the surface properties and flexibility of the resin.

Summary: We present a simple and cost-effective method to coat a thin hydrophobic film for various applications. By evaporating silicone rubber and hydrolyzing it on a TiO2 substrate, a hydrophobic layer is formed. The hydrophobic -Si (CH3)3 groups attach to the substrate by reacting with hydrophilic -Si-OH groups on the TiO2 surface. Additionally, the silicone film is utilized as a passivation layer in a perovskite solar cell, improving the perovskite layer's crystallinity, grain size, and stability. The optimized cell exhibits an energy conversion efficiency of 17.42% with FF, VOC, and JSC values of 73.76%, 1.1 V, and 21.39 mA/cm-2, respectively.

Summary: This study investigates the wettability of ZnO-T coatings in relation to surface morphology and DLC:SiOx film parameters. ZnO-Ts with different leg lengths show varying degrees of wettability, which can be further changed by keeping the samples in the dark at room temperature. DLC:SiOx films significantly enhance the hydrophobicity of ZnO-T coatings, and their thickness affects the surface roughness and hydrophobicity. Additionally, DLC:SiOx films provide protection against abrasion and light-induced effects. The results suggest that the largest ZnO-T fraction with a 40 nm thickness of DLC:SiOx film provides the best hydrophobicity, while the smallest ZnO-T fraction with a 120 nm thickness of DLC:SiOx film offers better mechanical durability. The detailed analysis conducted in this study can be beneficial for the application of other nanostructures with protective coatings in wettability control.

Summary: This study demonstrates the high catalytic efficiency of (3-aminopropyl)triethoxysilane (APTES) for the low temperature conversion of perhydropolysilazane (PHPS), and suggests the catalytic mechanism of APTES. The influence of temperature and humidity on the conversion process is investigated, and it is found that PHPS can be rapidly converted to silica at 80 degrees C with 90% relative humidity. The obtained silica coating has low volume shrinkage, low roughness, high nanoindentation hardness, and modulus, showing high potential as a protective coating for various materials, even those vulnerable to high temperature.
