摘要：Controllable fabrication of lightweight, highly conductive, and flexible films is important to simultaneously achieve excellent electromagnetic interference (EMI) shielding and high-rate energy storage. Herein, ultrathin, flexible, and conductive (up to 365,000 +/- 5000 S m(-1)) TOCNFs/CNT/Ti3C2Tx hybrid films were fabricated by a facile vacuum-filtration. The obtained films with 60 wt% Ti(3)C(2)T(x & nbsp;)content exhibited a high specific EMI SE of 9316.4 +/- 205.32 dB cm(2) g(-1), which was comparable to most of the other carbon-and MXene-based materials synthesized by complex steps. Additionally, the porous structure contributed to exposing more active sites and providing efficient transport of electrolyte ions. Consequently, the hybrid films showed a high areal capacitance and high specific capacitance of 537 mF cm(-2) and 279.7 F g(-1) at 0.3 mA cm(-2), respectively, together with impressive stability of 93.1% after 8000 cycles. This work provides an effective strategy to synthesize high-performance conductive films for applications in wearable or portable electronic devices.
