Abstract
- Facing the fast development of telecommunication technology, traditional electromagnetic wave absorbing materials are unable to meet the microwave shielding requirements in practical applications. Herein, a Ti<subscript>3</subscript>C<subscript>2</subscript>T<subscript>x</subscript> MXene/rGO composite aerogel was synthesized by facile hydrothermal and freeze-drying treatment. The prepared aerogel shows a unique porous three-dimensional network structure, which is of great advantage in improving its microwave absorption capability. Mixing Ti<subscript>3</subscript>C<subscript>2</subscript>T<subscript>x</subscript> and rGO adjusts the impedance match in the absorption process. When the weight ratio of Ti<subscript>3</subscript>C<subscript>2</subscript>T<subscript>x</subscript> to rGO is 1 : 6, the minimum reflection value (RL<subscript>m</subscript>) reaches −53.49 dB at 17.0 GHz (thickness = 2.2 mm), and the corresponding effective absorption bandwidth is 4.4 GHz (from 13.6 GHz to 18.0 GHz). rGO nanosheets of large size could retard the oxidation of Ti<subscript>3</subscript>C<subscript>2</subscript>T<subscript>x</subscript> to some extent. With its excellent microwave absorption performance, broad effective bandwidth, outstanding thermal resistance, and heat insulating properties, the composite aerogel has a great practical potential.
