Fabrication and measurement of the performance of a printed EMI shielding mesh filter on PET film

Preparation and oxidation behavior of Ag-coated Cu nanoparticles less than 20 nm in size

“…The technology has been widely applied to various elds such as radio-frequency identication (RFID) tags, 11,12 smart labels, 13 and electromagnetic interference (EMI) shielding. 14 Ag NPs have been extensively used as conductive metal NPs because of their lower resistance as compared to other metal NPs. 15 However, Ag is an expensive metal, and its high material cost has caused a bottleneck in ink-jet printing technology.…”

Recent advances and perspectives on silver-based polymer composites for electromagnetic interference shielding

“…Kim et al obtained a shielding mesh filter on PET film with an SE value of ∼22 dB by screen-printing AgNP ink. 141 Dijith et al researched the relationship between the patterns of AgNP coating and their SE and demonstrated that the SE increased, reaching up to 31 dB (at 8.2 GHz), when moving from a simple line pattern and mesh design to full coating. 142 Chun et al reported that mesh patterns of silver oxide pastes on PET films were obtained by continuous roll-to-roll printing at a speed of 1 m/min, and subsequently the resulting films were heated at 150 °C for 30 min to convert the patterned silver oxide pastes to silver patterns in the presence of Ag-neoalkanoates.…”

Review of carbon-based electromagnetic shielding materials: film, composite, foam, textile

“…The periodic structure of the film is mainly realized by the multilayer structure; a few studies have examined printing. [110][111][112] The interactions of the electromagnetic wave and material can be categorized into reflections, absorption, and multilayer reflections. The multilayer reflection depends mainly on the geometry of the shielding material.…”
