Experimental study demonstrates exceptional electromagnetic interference shielding in ultrathin MXene films, highlighting their utility for flexible protective coatings.

Key Points

To evaluate the electromagnetic interference shielding performance and electrical conductivity of two-dimensional transition metal carbides (MXenes) and their polymer composites in ultrathin film formats.
Fabricated free-standing films and polymer composites of titanium carbide (Ti3C2Tx) and related MXenes across different thicknesses.
Characterized electrical conductivity and measured electromagnetic interference shielding effectiveness for films ranging from 2.5 to 45 micrometers.
A 45-micrometer-thick Ti3C2Tx film demonstrated an electromagnetic interference shielding effectiveness of 92 decibels, while a 2.5-micrometer film achieved greater than 50 decibels.
Ti3C2Tx films exhibited an electrical conductivity of 4600 Siemens per centimeter, driving shielding through high conductivity and multiple internal reflections.
