Hierarchically Porous MXene/Carbon Nanotube/Epoxy Composites for Effective Electromagnetic Interference Shielding and Flame Retardancy

“…= T FGI PHRR/ PHRR (9) where TTI (s) is the ignition time. PHRR (kW/m 2 ) is the peak heat release rate.…”

“…Electronic devices are widely applied in various fields such as communication, automation, military, etc. − In these applications, polymers are one of the most used materials due to their advantages of being lightweight, easy to process, low cost, etc. , However, the insulated polymers are unable to shield the electromagnetic waves. In this case, the electromagnetic radiation generated by the use of electronic devices will seriously affect the stability of electronic devices and threaten human health. , To address this issue, designing a polymer-based composite by introducing functional filler in a polymer matrix for effective electromagnetic interference (EMI) shielding performance is an effective method. − Normally, the EMI shielding effect of the reported EMI shielding materials is mainly achieved through absorption and reflection. While reflecting electromagnetic waves will cause secondary pollution to the environment.…”

Simultaneously Enhancing Mechanical Strength, Toughness, and Fire Retardancy of Biobased Polyurethane by Regulating Soft/Hard Segments and Crystallization Behavior

“…Liu et al prepared a polyurethane nanocomposite material with excellent fire safety, mechanical performance, and electromagnetic interference (EMI) shielding by introducing cyclophosphazene-functionalized Ti 3 C 2 T x (CP-Ti 3 C 2 T x ), which acted as flame-retardant nanofiller, and carbon fiber fabric (CF), which functioned as a conductive filler. The tensile strength of TPU/CP-Ti 3 C 2 T x -2.0/CF was 43.2 MPa, and the ductility and toughness were improved by 28.4% and 84.3%, respectively, compared to those of TPU/CF . Chen et al separately synthesized cellulose acetate butyrate-modified ammonium polyphosphate (CAPP) and phosphoramide flame retardant-decorated short carbon fiber (MSCF) and then simultaneously blended them into thermoplastic polyurethane (TPU) to prepare a series of flame-retardant TPU composites.…”

Silver nanowires/cellulose flexible transparent conductive films for electromagnetic interference shielding and electrothermal conversion

“…1–5 The traditional metallic electromagnetic shielding material such as ITO, originally employed as a transparent conductive electrode, fails to satisfy contemporary requirements due to its exorbitant cost, fragility, and subpar quality. Later, researchers used Mxene, 6–13 graphene, 14–16 and carbon nanotubes 17–19 as the new electromagnetic shielding materials. For example, Ma et al 8 fabricated controllable multi-layer MXene composite films through the vacuum filtration method, enabling the multiple reflection and absorption of electromagnetic waves, thereby achieving an exceptional EMI SE of 58.0 dB.…”
