Abstract

Ti3C2Tx MXenes with excellent metallic conductivity and flexibility have shown a promising prospect as electromagnetic interference(EMI)shielding materials.Ultrathin,hierarchical hybrid films were fab-ricated by using C6o intercalating Ti3C2Tx MXenes with the assistance of water-soluble y-cyclodextrin(CD).The C60/CD complex was obtained by high-speed vibration milling using hydrophilic CD as dispers-ing agent.After thermal annealing treatment,the obtained hybrid film exhibited excellent EMI shielding(53.52±0.43 dB),hydrophobicity(water contact angle:93.7°)and mechanical stability(over 0.9 million bending times).Taking advantage of the antioxidant of C60,the chemical durability of Ti3C2Tx MXenes based hybrid films was also improved as expected.These results indicate that the well-designed hier-archical hybrid films with the intercalation of C60 have promising potential for high-performance EMI shielding applications.
