Summary: Controlled wetting of metallic surfaces is achieved through laser processing and surface coating. The study demonstrates the micro/nano-texturing of an aluminum surface with a nanosecond laser and the possibility of tuning the repelling properties. An inexpensive, environment-friendly, and simpler surface treatment for superhydrophobicity is developed, providing an alternative to traditional coatings. The surfaces show good performance and self-cleaning properties.

Summary: Superamphiphobic surfaces with extremely high contact angles and low contact angle hysteresis for both water and low-surface-tension liquids can be fabricated by a spray method of fluorinated multi-walled carbon nanotubes. These surfaces exhibit robust self-cleaning and abrasion resistance properties, maintaining outstanding superamphiphobicity even after exposure to harsh conditions.

Summary: In recent years, as non-biodegradable single-use plastic packaging products have been restricted, paper-based materials have gained attention for their environmental benefits. However, the hydrophilic nature of paper-based materials limits their use as replacements for non-biodegradable plastics. In this study, a superhydrophobic paper was developed using silane-modified nanofibrillated cellulose, which showed excellent water repellency, durability, and antibacterial properties. This durable and multifunctional superhydrophobic paper provides a novel solution to reduce white pollution and opens up new possibilities for the applications of paper-based materials.

Summary: This study demonstrates that the amount of fluorocarbon in omniphobic coatings can be significantly reduced by adsorbing hybrid hydrocarbon and fluorocarbon carboxylate chains onto nanoparticles, while maintaining the coating properties. This approach can substantially enhance the omniphobicity of the coatings.

Summary: In this study, a robust surface with superhydrophobic properties was prepared on stainless steel mesh by electrodeposition combined with low surface energy modification method. The experimental results showed that the synergistic effect of dense petal-like micro-nano rough structures and stearic acid modification on the surface of the mesh endowed it with good superhydrophobicity and excellent performance.

Summary: This study described three simple and environmentally friendly methods for surface treatment of aramid fiber. The results showed that the mechanical properties of composites with coated aramid fiber were significantly improved compared to those with aramid fiber treated by thermal oxidation, although the heat generation was higher. The thermal oxidation method not only improved the constant elongation stress and tear strength, but also reduced the heat generation of the materials.

Summary: The capacitive multitouch sensing surface developed using conductive graphene nanoparticles-based ink with carboxymethyl cellulose as a binder meets the increasing demand for transparent, flexible, and easy printable materials for sensing applications. The characteristics of the printed lines are optimized based on the line width and number of printing steps, with the optimal conditions leading to an electrical resistance of 2.4 k omega. The printed flexible touchscreen, composed of 40 columns x 28 rows, also features an electric circuit and graphic interface for multitouch capabilities and fast signal processing.

Summary: This study reports the fabrication of pH-responsive hydrogel coatings with microstructured wrinkles from a monomer mixture through atmospheric-pressure plasma polymerization. The hydrogels showed high conversion degree and preserved the functionalities of both monomers. Atomic force microscopy was used to characterize the wrinkle dimension, which increased with the film's thickness. The hydrogel films maintained their chemical and morphological properties even after immersion in deionized water for several days, demonstrating high stability. The simplicity of atmospheric-pressure plasma polymerization enables the deposition of highly stable and tunable hydrogels, which will extend their applications in biomedical fields.
