N2 - A polydimethylsiloxane/copper nanowires(PDMS/CuNWs) composite film was prepared by an environmental-friendly glucose templating method and an improved wet chemical reduction method. PDMS/CuNWs composite adopts a “sandwich-like structure” design. It effectively solves the problem that copper is easily oxidized in the air, which leads to a significant drop in electrical conductivity. At the same time, a bifunctional lightweight and flexible composite film with excellent electromagnetic shielding and photothermal conversion properties is obtained. The performance retention rate of the composite film with an CuNWs area density of 1.6 g/cm2 can reach up to 99.07% after 1000 repeated bending times; the total electromagnetic shielding efficiency of the composite film with an area density of 2.4 g/cm2 in the X-band reaches 30.1 dB, and the shielding efficiency reaches 99.9%; meanwhile, under the irradiation of near-infrared light of 2 W/cm2, the surface temperature of the composite film is as high as 211.2 °C after heating for only 15 s. PDMS/CuNWs composite has a very fast photothermal response and conversion efficiency.
