Abstract The increasing demand for multifunctional materials that combine electromagnetic wave (EMW) absorption and antibacterial properties has driven the development of novel capable meeting these challenges. Here, a core–shell Ce/NiCo@C composite with radial dielectric gradient structure is presented, designed to enhance EMW exhibit potent activity. material's unique architecture, which includes multilayered configuration distribution Ce 3+ /Ce 4+ valence states, modulates constant promotes electron migration polarization under exposure. This design results in broad effective bandwidth 7.12 GHz, minimum reflection loss (RL min ) −67.2 dB at thickness 1.94 mm. Additionally, reversible transition between generates reactive oxygen species (ROS), disrupt microbial cell membranes inhibit bacterial growth. demonstrates sterilization rate exceeding 99% against E. coli significant bactericidal effect S. aureus . work highlights potential integrating valence‐modulated, advanced antimicrobial applications, offering promising approach future diverse technological fields.

To enhance the anticorrosive performance of coatings in harsh corrosive environments, a graphene/isophorone diisocyanate (IPDI) microcapsule is prepared by in-situ polymerization. The self-healing and based on these microcapsules are studied. with cross-linked shells this study solves problems excessive size insufficient strength traditional microcapsules. addition improves coatings. shape form round balls, average particle thickness range 17–23 μm 0.5–3.4 μm, which conducive to preparation 20.64 MPa wrap-around rate reaches 68%. have an initial evaporation temperature 231.3 °C, graphene organic cross-linking shell enhances thermal stability electrochemical impedance spectroscopy (EIS) indicates that |Z|f=0.01 Hz value coating 10 wt% after 168 h immersion about 9.4 × 109 Ω cm2, nearly three orders magnitude higher than without (6.9 106 cm2). Monitoring artificial scratches using scanning electron microscope (SEM) for 24 reveals repairs cracks well. It demonstrated incorporation graphene/IPDI anti-corrosive coating.
