Silver nanowire (Ag NW) has been considered as the promising building block for the fabrication of transparent electromagnetic interference (EMI) shielding films. However, the practical application of Ag NW-based EMI shielding films has been restricted due to the unsatisfactory stability of Ag NW. Herein, we proposed a reduced graphene oxide (rGO) decorated Ag NW film, which realizes a seamless integration of optical transparency, highly efficient EMI shielding, reliable durability and stability. The Ag NW constructs a highly transparent and conductive network, and the rGO provides additional conductive path, showing a superior EMI shielding effectiveness (SE) of 33.62 dB at transmittance of 81.9%. In addition, the top rGO layer enables the hybrid film with reliable durability and chemical stability, which can maintain 96% and 90% EMI SE after 1000 times bending cycles at radius of 2 mm and exposure in air for 80 days. Furthermore, the rGO/Ag NW films also possess fast thermal response and heating stability, making them highly applicable in wearable devices. The synergy of Ag NW and rGO grants the hybrid EMI shielding film multiple desired functions and meanwhile overcomes the shortcomings of Ag NW. This work provides a reference for preparing multifunctional integrated transparent EMI shielding film.

Electromagnetic interference (EMI) shielding materials with excellent flexibility and mechanical properties and outstanding thermal conductivity have become a hot topic of research in functional composites. In this study, the "sol-gel-film conversion technique" is used to assemble polyetherimidefunctionalized Ti 3 C 2 T x nanosheets (f-Ti 3 C 2 T x ) with poly(p-phenylene-2,6benzobisoxazole) (PBO) nanofibers (PNFs), followed by dialysis and vacuum drying to prepare f-Ti 3 C 2 T x /PNF films with lamellar structures. When the loading of f-Ti 3 C 2 T x is 70 wt%, the f-Ti 3 C 2 T x /PNF film presents optimal comprehensive properties, with an EMI shielding effectiveness (SE) of 35 dB and a specific SE/thickness ((SSE, SE/density)/t) of 8211 dB cm 2 /g, a tensile strength of 125.1 MPa, an in-plane thermal conductivity coefficient (λ) of 5.82 W/(m K), and electrical conductivity of 1943 S/m. After repeated folding for 10,000 cycles, the EMI SE and the tensile strength of f-Ti 3 C 2 T x /PNFs films still remain 33.4 dB and 116.1 MPa, respectively. Additionally, the f-Ti 3 C 2 T x /PNF film also shows excellent thermal stability, flame retardancy, and structural stability. This would provide a novel method for the design and fabrication of multifunctional composite films and considerably expand the applications of MXene-and PNF-based composites in the fields of EMI shielding and thermal management.

Materials with strong electromagnetic absorption capacity and strong ultraviolet (UV) resistance have become an increasing requirement for the nextgeneration of multifunctional textiles. Herein, cotton fabric composites with ultra-high-efficiency electromagnetic shielding and UV resistance are provided by decorating zinc oxide (ZnO) on silver nanowires (AgNWs). ZnO modified AgNWs (ZnO@AgNWs) were prepared first, followed by filling into waterborne polyurethane (WPU) to form ZnO@AgNWs/WPU, which was used to prepare multifunctional cotton fabric composites by spreading ZnO@AgNWs/ WPU evenly on cotton fabric by hand coating. The electromagnetic shielding properties of the composites were measured at the frequency range of 0.3-3000 MHz. The results showed that the maximum electromagnetic interference shielding effectiveness (EMI SE) value of ZnO@AgNWs/WPU/cotton fabric composite was 32 dB. The neat AgNWs were also used to enhance the electromagnetic shielding. The EMI SE of ZnO@AgNWs/WPU/cotton fabric composite was 52.38% higher than AgNWs/WPU/cotton fabric composite. In addition, the ZnO@AgNWs/WPU/cotton fabric composite presents well UV protecting ability. The tensile strength of cotton fabric increased 30.
