A multifunctional electronic skin with thermal radiation regulation and electromagnetic interference (EMI) shielding is urgent for electronic systems because of the thermal radiation emission and electromagnetic wave pollution. Herein, a flexible electronic skin was designed and fabricated, where the polyaniline (PANI) served as the functional layer and Ti 3 C 2 T x MXene was employed as the conductive electrode. The transformation of emeraldine salt (ES) and leucoemeraldine base (LB) of PANI makes the skin achieve an infrared emissivity modulation, and the electromagnetic loss of PANI and ultrahigh electrical conductivity of Ti 3 C 2 T x MXene make it exhibit EMI shielding ability. Benefiting from the special structural design, the multifunctional skin with a small thickness (0.3 mm) and low surface density (0.06 g/cm 2 ) exhibits an excellent infrared emissivity modulation ability (Δε) of 0.32 with emissive power of 119.1 W/m 2 at the wavelength range of 2.5−25 μm and total shielding effectiveness (SE T ) of 36.3 dB over the X-band (8.2−12.4 GHz). Meanwhile, the multifunctional skin remains black in the visible spectrum but a changeable color in the infrared spectrum. Even after repeated bending and twisting, the multifunctional skin still maintains a good emissivity adjustment. The simultaneous realization of dynamic thermal radiation regulation and EMI shielding endows the skin promising potential for various fields, such as adaptive infrared camouflage, thermal regulation, anticounterfeiting, and EMI shielding-related crossing field.

MXenes are the new members in the family of two-dimensional (2D) layered materials composed of transitional metal carbides, nitrides, or carbonitrides. Among all other MXenes, Ti3C2T x MXene is the most studied one due to the exceptional properties that make it suitable for various applications, including optoelectronics. Ti3C2T x MXene can be fabricated and processed in a variety of scalable and cost-effective ways. MXenes are solution-processable materials that can be deposited by spin, spray, or dip coating, painting, or printing. They exhibit excellent optical transparency, high metallic conductivity, efficient photothermal conversion, plasmonic behavior, and tunability of the optical response over traditional 2D materials. These features have led to a fast evolution of this material with many explorations of its applications in the field of optoelectronics. This short review summarizes the recent updates on the synthesis, optical, as well as electronic properties, and the various optoelectronic applications of Ti3C2T x MXene in the materials point of view. The challenges to be overcome for their successful integration into the optoelectronics domain and opportunities for future explorations are also discussed.

Polyaniline (PANI) can achieve reversible optical modulation in visible and infrared (IR) bands under the action of voltage. However, PANI‐based electrochromic devices cannot cope with the dual detection of visible and IR light to realize the transmission of information due to the linkage restriction between the spectral modulation in the visible and IR region. Here, IR low‐absorptive inorganic pigments as colorants and IR high‐transparent polymer as a binder are utilized to prepare colored films with high transparency. A camouflage layer against visible light detection is constructed on the surface of IR electrochromic devices, and the information transmission is realized in the IR band by controlling the thermal radiation characteristics. Furthermore, thermochromic microcapsules (TMs) that change color under external thermal stimuli are introduced to fabricate a thermochromic and IR transparent functional layer, which is attached to the surface of IR electrochromic devices and endows the devices with separate spectral modulation ability in the visible and IR region. Multicolored displays are fabricated by arraying various devices. Moreover, visual patterns are prepared on the surface of IR electrochromic devices by dispensing technology. This configuration endows the device with a promising potential for anti‐counterfeiting, optical security, and related applications.
