Summary: A self-regenerating antibacterial surface has been developed by depositing alternating layers of antibacterial and biodegradable coatings using a solvent-free initiated chemical vapor deposition method. This surface can regenerate its function after contamination by shedding off top layers and exposing fresh antibacterial surfaces. The designed self-regenerating surfaces could resist biofilm formation and extend the service life of indwelling medical devices.

Summary: One-hundred-nanometer films composed of silver, copper, and gold nanocrystallites were prepared and their antibacterial properties were quantitatively measured. The research showed significant oxidation of the copper films and ranked the antibacterial efficacy as Ag/Cu > Au/Cu > Cu. This suggests that such metallic surfaces could be utilized as contact-killing materials for better defense against bacteria and viruses.

Summary: In this work, a simple, fast, and efficient strategy to fabricate high-performance rigid crosslinked PVC composites by continuous extrusion is proposed for the first time. This strategy solves the problems of poor processing fluidity of composites and the impossibility of conducting extrusion in one step by using microcapsule-type crosslinking agents prepared by in situ polymerization to co-extrude with PVC blends. The results demonstrate successful preparation of PVC/microcapsule composites, with improved properties of crosslinked PVC by the addition of microcapsules, including an increased Vicat softening temperature from 79.3°C to 86.2°C compared to pure PVC. This study shows the possibility for industrial scale-up of the extrusion process for rigid crosslinked PVC.

Summary: A new method using acrylate click chemistry is proposed to fabricate highly durable and eco-friendly superhydrophobic surfaces. The use of long-chain acrylates provides extreme water repellency, and the resulting surfaces exhibit long-term stability under various harsh conditions. This technique results in highly robust 3D superhydrophobic surfaces that can be easily molded or sprayed onto various substrates.

Summary: Zirconium-based bulk metallic glasses (Zr-BMGs) with biomimetic structures were created using femtosecond laser, and their antifouling and antibacterial properties were evaluated. The results showed that the rice leaf-like and butterfly wing-like structures had the best antifouling effect, while the shark skin-like structure exhibited the highest bactericidal performance. Crystallization was observed on the surfaces with laser energy intensities greater than 2.38 J/mm2, but the substrate remained amorphous. The Nepenthes-like structure with disordered nano bulges showed the best balance between antifouling, bactericidal, and biocompatibility. These laser fabricated biomimetic structures can enhance the antibacterial activity of Zr-BMG medical devices, thereby improving medical treatment quality.

Summary: Hot-water repellency on traditional superhydrophobic surfaces is challenging due to the formation of liquid bridges between tiny droplets and the substrate. In this study, a facile and fluorine-free vapor-deposition method was proposed to fabricate excellent hot-water-repellent surfaces. The surfaces showed outstanding repellency to hot water droplets and other normal-temperature droplets with high surface tension, and also demonstrated excellent self-cleaning performance in specific environments.
