Flexible multifunctional polymer-based electromagnetic interference (EMI) shielding composite films have important applications in the fields of 5G communication technology, wearable electronic devices, and artificial intelligence. Based on design a porous/multilayered structure using polyimide (PI) as matrix polymethyl methacrylate (PMMA) microspheres template, flexible (Fe3 O4 /PI)-Ti3 C2 Tx -(Fe3 /PI) with controllable pore sizes distribution Ti3 hollow are successfully prepared by sacrificial template method. Owing to structure, when size is 10 µm mass ratio PMMA/Ti3 2:1, film has most excellent EMI performance, effectiveness (EMI SE) 85 dB. It further verified finite element simulation that an effect waves. In addition, good thermal conductivity (thermal coefficient 3.49 W (m·K)-1 ) mechanical properties (tensile strength 65.3 MPa). This conductivity, demonstrated great potential for protection high-power, portable, devices.

Thermal conduction for electronic equipment has grown in importance light of the burgeoning 5G communication. It is imperatively desired to design highly thermally conductive fillers and polymer composite films with prominent Joule heating characteristics extensive mechanical properties. In this work, "solvothermal & situ growth" method carried out prepare "Fungal tree"-like hetero-structured silver nanowires@boron nitride nanosheet (AgNWs@BNNS) fillers. The AgNWs@BNNS/ANF are obtained by "suction filtration self-assembly hot-pressing". When mass fraction AgNWs@BNNS 50 wt%, film presents optimal thermal conductivity coefficient 9.44 W/(m ⋅ K) excellent tensile strength 136.6 MPa, good temperature-voltage response characteristics, superior electrical stability reliability, which promise a wide application potential devices.

High‑efficiency electromagnetic interference (EMI) shielding materials are of great importance for electronic equipment reliability, information security and human health. In this work, bidirectional aligned Ti3C2Tx@Fe3O4/CNF aerogels (BTFCA) were firstly assembled by freezing freeze-drying technique, the BTFCA/epoxy nanocomposites with long-range lamellar structures then prepared vacuum-assisted impregnation epoxy resins. Benefitting from successful construction three-dimensional conductive networks synergistic effect, when mass fraction Ti3C2Tx Fe3O4 2.96 1.48 wt%, show outstanding EMI effectiveness 79 dB, about 10 times that blended Ti3C2Tx@Fe3O4/epoxy (8 dB) same loadings Fe3O4. Meantime, corresponding also present excellent thermal stability (Theat-resistance index 198.7 °C) mechanical properties (storage modulus 9902.1 MPa, Young's 4.51 GPa hardness 0.34 GPa). Our fabricated would greatly expand applications MXene resins in fields security, aerospace weapon manufacturing, etc.

Electromagnetic interference (EMI) shielding is critical in electronic applications. However, the currently available EMI materials are restricted customizability and application flexibility. Recent advances manufacturing technologies have provided a unique path to achieve custom creation of solutions. A successful example additive (AM), which has enabled high design freedom, efficient performance regulation, multifunctionality simultaneously into fabricated shields, offering an opportunity start revolution field shielding. In this review, we summarize latest AM materials, aiming provide deep understanding connection between raw methods, considerations, performances shields. We first introduce mechanism subsequently focusing on characteristics representative methods as-created Based requirements create application-oriented solutions, these also critically compared. Thereafter, present state-of-the-art considerations shields examine pivotal roles realizing designs. conclude by discussing future research directions, at motivating use developments
