摘要：

Developing multifunctional transparent shielding films (TSFs) are highly desirable for the advanced visualization electronic devices. Herein, based on the excellent electrical conductivity of two-dimensional Ti3C2Tx (MXene), flexible hydrophobic MXene-based transparent conducting films are applied in the field of shielding electromagnetic wave and electrical heating. Typically, a spraying coupled with spinning technique is demonstrated to orderly deposit MXene and hydrophobic fumed silica (Hf-SiO2) on transparent polycarbonate (PC) for developing the multifunctional TSFs. The obtained sandwich structural PC/MXene/Hf-SiO2 film exhibits the balanced optical and electrical properties with a low electrical resistance of 35.1 Omega/sq and corresponding transmittance of 33.4%, showing an effective electromagnetic interference shielding effectiveness (EMI SE 20 dB) combined with a rapid steady joule heating performance at safe voltages (similar to 100 degrees C at 13 V), simultaneously. Meanwhile, the superhydrophobic Hf-SiO2 coating layer not only endows the film with excellent self-cleaning ability, but also prevents MXene from oxidation. As a result, the hydrophobicity, conductivity and shielding performance of this film can steadily maintain in outdoor conditions for 100 days. Besides, outstanding flexibility gives the film with superior mechanical fatigue resistance (<10% resistance change after mechanical bending 1000 cycles). This work opens a new avenue for preparing next-generation multifunctional TSFs to meet the various application environments.
