Traditional conductive fabrics are prepared by the synthesis of conductive polymers and the coating modification of metals or carbon black conductive materials. However, the conductive fabrics cause a significant decline in performance after washing or mechanical wear, which limits their application. Moreover, the single function of the traditional conductive fabric is also the reason that limits its wide application. In order to prepare a wearable, stable, high-performance, washable, multifunctional conductive fabric, we have carried out related research. In this work, polydopamine was used as a bonding layer, an adsorption reduction layer, and a protective layer to improve the bonding between silver nanoparticles and carbon nanotubes (CNTs) on the polyester fabric surface so as to prepare a multifunctional conductive fabric with a high-stability "sandwich" structure, in which a Ag-NPS@CNT structure acting as an intermediate conductive layer formed on the inner layer PDA@CNT by electroless silver plating and the outermost layer PDA@ CNT coated on the surface of the intermediate conductive layer by the impregnation-drying method. The sheet resistance of an E-Fabric can reach 2.11 Ω/□ due to the uniform and dense conductive path formed by the special structure Ag-NPs@CNT. At a low voltage of 1.5 V, the E-Fabric can reach 117 °C in 50 s and remain stable. The electrical conductivity and current heating properties of the E-Fabric remain good even after multiple washing or bending tests. Due to its stable and outstanding electrical conductivity, the E-Fabric has an electromagnetic shielding efficiency (SE T ) of 35.3 dB in the X-band (8.2−12.4 GHz). In addition, E-Fabricbased spin-coated poly(methyl methacrylate) or polydimethylsiloxane electrodes exhibit excellent performance in nanogenerators. Through the low-frequency friction of the human body, transient voltages up to 4 V can be generated from a 2 cm × 2 cm electrode sample. The output power of a single generator can reach about 12 nW/cm 2 . Therefore, an E-Fabric is considered to have great potential in the fields of electric heating, electromagnetic shielding, and smart wearable devices.

Flexible transparent conductive films currently have been an extremely critical part of various optoelectronic devices. Herein, single-walled carbon nanotubes were non-covalently modified with ellagic acid to obtain modified carbon nanotubes (ECNTs), and p-type doping of gold nanoparticles was achieved on ECNT films utilizing the HAuCl4 solution (Au-ECNTs). Afterward, Au-ECNT/PEDOT:PSS bilayer films which possess excellent optoelectronic performance were fabricated through compositing with a highly conductive polymer poly(3,4-ethylenedioxythiophene):poly(styrene sulfonate) by means of spin-coating. The film displayed outstanding optoelectronic performance (R s = 42.5 Ω/sq@T = 79.8%), a rather smooth surface (roughness = 3.81 nm), superior mechanical strength (ΔR = 0.1 after 1000 times of bending cycle tests), and satisfactory adhesion (f T = 0.87). Finally, the film was employed as an anode to construct organic light-emitting diode devices with a maximum luminance of 2567 cd/m2 and a maximum current efficiency of 5.16 cd/A obtained at a 11 V voltage, which demonstrated that this type of film owns promising application prospects in the future photovoltaic device field.
