Flexible and Waterproof 2D/1D/0D Construction of MXene?Based Nanocomposites for Electromagnetic Wave Absorption, EMI Shielding, and Photothermal Conversion
摘要
Abstract
High-performance electromagnetic wave absorption and electromagnetic interference (EMI) shielding materials with multifunctional characters have attracted extensive scientific and technological interest, but they remain a huge challenge. Here, we reported an electrostatic assembly approach for fabricating 2D/1D/0D construction of -Ti3C2Tx/carbon nanotubes/Co nanoparticles -(Ti3C2Tx/CNTs/Co) nanocomposites with an excellent electromagnetic wave absorption, EMI shielding efficiency, flexibility, hydrophobicity, and photothermal conversion performance. As expected, a strong reflection loss of -85.8 dB and an ultrathin thickness of 1.4 mm were achieved. Meanwhile, the high EMI shielding efficiency reached 110.1 dB. The excellent electromagnetic wave absorption and shielding performances were originated from the charge carriers, electric/magnetic dipole polarization, interfacial polarization, natural resonance, and multiple internal reflections. Moreover, a thin layer of polydimethylsiloxane rendered the hydrophilic hierarchical -Ti3C2Tx/CNTs/Co hydrophobic, which can prevent the degradation/oxidation of the MXene in high humidity condition. Interestingly, the -Ti3C2Tx/CNTs/Co film exhibited a remark able photothermal conversion performance with high thermal cycle stability and tenability. Thus, the multifunctional -Ti3C2Tx/CNTs/Co nanocomposites possessing a unique blend of outstanding electromagnetic wave absorption and EMI shielding, light-driven heating perfor-mance, and flexible water-resistant features were highly promising for the next-generation intelligent electromagnetic attenuation system.关键词
