Summary: In this study, copper-loaded antibacterial glasses were prepared using an ion-exchange method, and the effects of different molten salts and ion exchange duration on their antibacterial properties were investigated. The results showed that the glasses exchanged with CuSO4/Na2SO4 mixed molten salts had a higher surface copper loading. The antibacterial function of the glass samples was found to be related to the charge transfer and the content of Cu+ ions on the glass surface.

Summary: Smart and controllable antibacterial fabrics have great potential in textile, medical, and healthcare fields. In this study, a composite antimicrobial fiber with thermally responsive properties was created by synthesizing nano zinc oxide (ZnO) and combining it with quaternary ammonium chitosan (QAC). The addition of a copper sulphide (CuS) layer further enhanced the antibacterial properties of the materials. These smart responsive composite fibers show promise in medical dressings, special textiles, and healthcare materials.

Summary: Water pollution is a globally concerned environmental issue. A novel filtration membrane called magnetic ion-imprinted membrane (MIIM) based on electro-spun polyacrylonitrile (PAN) was developed to simultaneously remove heavy metal ions and microorganisms from wastewater. The MIIM exhibited efficient Pb(II) ions removal (45.4 mg center dot g(-1)), excellent cycling performance (about 79.0 %), and high antibacterial properties (>90% killing rate for E. coli and S. aureus). The results suggest that MIIM has great potential for treating polluted water.

Summary: A composite film for chilled meat packaging was synthesized by self-assembly of zinc ions with chelating carboxyl groups, providing excellent water resistance and antibacterial properties. The composite film demonstrated enhanced mechanical properties due to the formation of chelation bonds. Chilled meat preservation tests showed that the composite film can significantly extend the shelf life of pork by five days, offering a potential solution to the short shelf-life problem.

Summary: This study prepared small-diameter polyurethane artificial blood vessels through electrospinning and improved their biological properties through plasma treatment. The results showed that plasma treatment increased the proportion of oxygen-containing functional groups on the sample surface, improved its wettability, and promoted cell infiltration and proliferation. Additionally, plasma treatment reduced the risk of platelet adhesion. However, longer plasma treatment time led to decreased mechanical properties of the samples.
