To avoid bacterial and viral infections on food products, the use of antibacterial and antiviral packaging offers great benefit to the food industry. In this study, the coating of paper packaging with silver-decorated magnetic particles (Ag@Fe 3 O 4 ) was developed. The Ag@Fe 3 O 4 was prepared by a facile and environmentally friendly method using extracted spent coffee grounds (ex-SCG). The effects of Ag@Fe 3 O 4 content on properties of coated paper were investigated. The overall properties of coated paper improved when the Ag@Fe 3 O 4 content increased up to 0.15%w/v. An increase in tensile strength of 154.01% and a decrease in water vapor permeability of 48.50% were found in coated paper with 0.15%w/v Ag@Fe 3 O 4 . Furthermore, the coated paper also exhibited the synergistic effect on antibacterial activities against Escherichia coli ( E. coli ) and Staphylococcus aureus ( S. aureus ). The release of metal ions in food simulants and kinetic release parameters were also studied. The release of silver ions and ferrous ions in food simulants met the requirement of overall migration limit of the European Standard. The paper coated with 0.15%w/v Ag@Fe 3 O 4 had better capabilities to maintain quality and extend shelf-life of tomatoes. The obtained Ag@Fe 3 O 4 coated paper is promising for bioactive food packaging to retain food freshness.

“…Li et al successfully developed a biodegradable paper-based material composed of an electromagnetic wave loss layer (graphene/silver nanoparticles (AgNPs) coating) and a reflective layer (Al film). In the range of 8-13 GHz, the material exhibits an exceptionally high electromagnetic interference shielding effectiveness (EMI SE) of 92.29 dB [8]. Previous research have reported that magnetic metals, such as nickel-iron (Ni-Fe) alloys, are highly effective for shielding through absorption.…”

In this study, aluminum and aluminum/nickel metal layers with varying thicknesses were deposited on the surface of epoxy resin using electron beam evaporation technology. The research aimed to explore and compare the impact of the thickness and material of the metal layer on electromagnetic interference shielding efficiency. The study revealed that the metal layer on the pre-treated surface of the epoxy resin displays a more complete morphology with uniform coverage and a distinctive stratification in the aluminum/nickel (Al/Ni) metal layer. The application of aluminum and aluminum/nickel metal layers onto the surface of epoxy resin demonstrates effective electromagnetic interference shielding. The investigation reveals that electromagnetic interference shielding efficiency escalates with the thickness of the metal layer within the test frequency range of 4 GHz to 15 GHz. Notably, it attains 70 dB when the aluminum/nickel metal layer achieves a thickness of 1 μm. These findings signify that the aluminum/nickel metal layer displays outstanding electromagnetic interference shielding performance, making it suitable for widespread application in the domain of electromagnetic interference shielding for polymer composites.

Recycling every viable material to produce new value-added products not only reduces waste, but also provides an opportunity to create sustainable and innovative solutions while preserving our natural resources. With this motivation, electrically conductive one-dimensional carbon fibers and two-dimensional aluminum flakes reinforced cellulose matrix composite papers were manufactured using recycled materials with a scalable, eco-friendly, and low-cost papermaking process. The designed composite paper showed 36.1 dB electromagnetic interference shielding efficiency (EMSE) with an absorbance-dominated performance by absorbing 98.85% of electromagnetic waves. An efficient impedance matching was obtained on the composite paper surface using reinforcements with different morphologies. Cellulose paper samples were converted to electrically conductive composites (0.415 S/cm), and the electrical conductivity was altered by tailoring the reinforcement ratios. Thermo-mechanical test results revealed that the cellulose matrix’s storage modulus was increased from 1.44 to 2.1 GPa with a 46.5% improvement. The composite cellulose paper represented increased hydrophilicity with higher porosity. The environmentally friendly composite paper responses to the escalating environmental worries and possesses a tremendous possibility of being utilized as an electromagnetic shielding material.
