Flexible Ti₃C₂T _x /(Aramid Nanofiber/PVA) Composite Films for Superior Electromagnetic Interference Shielding.

ABSTRACT: Multifunctional electromagnetic interference (EMI) shielding materials would solve electromagnetic radiation and pollution problems from electronic devices. Herein, the directional freeze-drying technology is utilized to prepare the aramid nanofiber/polyvinyl alcohol aerogel with a directionally porous structure (D-ANF/PVA), and the Ti₃C₂T _x dispersion is fully immersed into the D-ANF/PVA aerogel via ultrasonication and vacuum-assisted impregnation. Ti₃C₂T _x /(ANF/PVA) EMI shielding composite films with directionally ordered structure (D-Ti₃C₂T _x /(ANF/PVA)) are then prepared by freeze-drying and hot pressing. Constructing a directionally porous structure enables t
