| Abstract Scope |
Next generation wearable and portable electronic devices is in dire need of free-standing films which should be lightweight, flexible, conductive and environmentally stable. However, achieving these properties with pristine polymer is challenging due to its lack of conductivity. To address this issue, a multifunctional free-standing composites film based on Ti3C2Tx MXene and polystyrene (PS) is developed. In this work, the Ti3C2Tx MXene content varied as 0.5, 1.0, 1.5 and 2.0 wt.%. Microstructural characterization revealed uniform dispersion of Ti3C2Tx MXene in PS matrix till the content of 2 wt.%. Healing response while exposed to NIR demonstrated improved healing efficiency with increasing MXene loading, consistent with stronger photothermal conversion. Mechanical and cyclic bending tests confirmed the flexibility and the structural stability of the films with robust performances. These results highlight the potential of MXene/PS nanocomposite for flexible electronics, and wearable sensors. |
