    Area of Science:

    • Materials Science
    • Nanotechnology
    • Electromagnetics

    Background:

    • Titanium carbide (Ti3C2Tx) MXene exhibits excellent dielectric properties for electromagnetic (EM) wave absorption and shielding.
    • High loading of Ti3C2Tx is typically required for high-performance EM wave absorption and shielding, limiting its application in lightweight devices.
    • Optimizing the dielectric properties of Ti3C2Tx is crucial for developing lightweight EM wave protection materials.

    Purpose of the Study:

    • To optimize the dielectric properties of Ti3C2Tx MXene for enhanced EM wave absorption and shielding.
    • To explore the effect of in situ grown TiO2 nanoparticles on the EM wave attenuation capabilities of Ti3C2Tx.
    • To provide a guiding approach for the application of modified Ti3C2Tx in lightweight EM wave protection.

    Main Methods:

    • Annealing Ti3C2Tx in a nitrogen atmosphere to achieve in situ growth of TiO2 nanoparticles on the Ti3C2Tx surface.
    • Modulating the crystal form and size of TiO2 nanoparticles by varying annealing temperatures (350 °C and 500 °C).
    • Characterizing the dielectric properties and evaluating the EM wave absorption and shielding performance of the modified materials.

    Main Results:

    • Annealing at 350 °C produced anatase-type TiO2 nanoparticles (TiO2-A-NP), improving impedance matching and interfacial polarization, leading to a 117% increase in effective absorption bandwidth for a 1 mm-thick sample.
    • Annealing at 500 °C formed anatase-rutile TiO2 heterojunctions (TiO2-AR-HJ), significantly increasing conductivity and improving the average total EM shielding effectiveness by 45.9%.
    • The annealing process effectively tuned the dielectric properties of Ti3C2Tx, enhancing its performance in EM wave absorption and shielding.

    Conclusions:

    • In situ modification of Ti3C2Tx with TiO2 nanoparticles via annealing is an effective strategy to enhance EM wave absorption and shielding.
    • Controlling TiO2 nanoparticle characteristics (crystal form, size, heterojunctions) through annealing temperature allows for tailored dielectric properties and EM wave attenuation.
    • This approach offers a promising route for developing advanced, lightweight Ti3C2Tx-based materials for electromagnetic protection applications.
