“…These peaks are assigned to the (100), (002), (101), (102), (110), (103), and (112) planes of the wurtzite phase of ZnO, as reported in the literature 61 . The XRD patterns of the ZnO/Ag antibacterial agents had four new diffraction peaks at 2θ = 38.2°, 44.3°, 64.5°, and 77.5°, corresponding to (111, 200, 220, 311) of metallic silver, confirming the existence of zero‐valent silver 62 . Ag ions may be impossible to replace themselves in the ZnO matrix crystal lattice.…”

Melt blending is considered a significant method to develop antibacterial textile materials. However, it is still challenging to the homogeneous dispersion and efficient antibacterial activity of inorganic nanoparticles in polymer fibers. In this work, ZnO/Ag@SiO2 inorganic nanohybrid antibacterial agents were prepared by the direct precipitation method. The prepared antibacterial material had efficient antibacterial and thermal stability properties. Specifically, the decomposition temperature of the ZnO/Ag@SiO2 was higher than 400°C, which was appropriate for melting polymers at high temperatures. Here, polyethylene terephthalate (PET) was used as a fiber matrix, and PET/ZnO/Ag@SiO2 fibers were prepared by melt spinning technology. The results showed that the antibacterial material was well dispersed in the PET matrix, and the crystallization was promoted during the cooling process. The modified PET fibers presented better antibacterial properties against Escherichia coli (E. coli) and Staphylococcus aureus (S. aureus), with a maximum antibacterial rate of 99.9%. Additionally, the modified PET fibers provide superior laundering durability, with an antibacterial rate of 95.7% for S. aureus and 94.8% for E. coli after 50 washes. This work offers a novel approach to preparing thermotolerant and efficient antibacterial agents and antibacterial‐modified PET fibers.Highlights ZnO/Ag@SiO2 nanohybrid antibacterial agents were prepared. High temperature resistant and highly antibacterial material. The particles dispersed uniformly in PET matrix. Excellent antibacterial and laundering properties of the fiber

“…Due to the advantages of simple LbL assembly process, applied to different building blocks and substrates, and customizable film structure and thickness, the LbL assembly technique is heavily used in the preparation of anticorrosion coatings. [7][8][9][10][11][12][13] Polymer coatings are prepared by depositing functional materials. Often these functional materials do not bond effectively with the substrate being deposited and current techniques usually require plasma, corona, chemical or even flame and thermal steps.…”

Self‐healing coatings offer tremendous application prospects in the field of preventing metal corrosion because of their superior functionality. The coordination of barrier performance and self‐healing ability, however, continues to be difficult. Herein, a polymer coating based on polyethyleneimine (PEI) and polyacrylic acid (PAA) with self‐repairing and barrier ability was designed. Introducing the catechol group into the anti‐corrosion coating increases the adhesion and self‐healing efficiency of the coating, providing a guarantee for the long‐term stable bonding between the anti‐corrosion coating and the metal substrate. Small molecular weight PAA polymers are added to polymer coatings to increase their self‐healing capabilities and corrosion resistance. Because layer‐by‐layer assembly creates reversible hydrogen bonds and electrostatic bonds that help the coating repair itself when it is damaged, and because the traction of small molecular weight polyacrylic acid speeds up this process. When polyacrylic acid (PAA) with a molecular weight of 2000 was present in the coating at a concentration of 1.5 mg/mL. The PEI‐C/PAA45W‐PAA2000 coating has the fastest self‐healing, and the corrosion resistance efficiency (Pe) was as high as 90.1%. The polarization resistance (Rp) was maintained at 7.67×104 Ω∙cm2 after immersion for more than 240 h. It was better than other samples in this work.
