Military tents are crucial for military operations. Existing military tents use insulating and photonically inert textiles, which cannot be used as electric or light-driven heaters, significantly restricting their application in high-altitude combat zones. Considering the simultaneous threats of rain, snow, electromagnetic radiation and bullet impact in the battlefield, a kind of multifunctional protective material is necessary for military tents. In this paper, a multifunctional material including MXene as the functional layer, nylon fabric as the base material, and room temperature vulcanized silicone rubber as the surface waterproof layer is developed. The results show that: Results show that the synergistic effect of MXene and silicone rubber modifies the surface roughness and surface energy of pure nylon fabric, increasing its hydrophobic contact angle from 38.3° to 105.3°. MXene can form continuous conductive networks on fabric surfaces at varying concentrations. The electromagnetic shielding effectiveness of MXene and silicone rubber modified nylon (MS-Nylon) in the X-band spectrum increases to 17.64 dB to 18.54 dB when the mass fraction of MXene reaches 18.87%. Concurrently, the fabric's photothermal performance was significantly enhanced. Comparing with Nylon without photothermal property, the surface temperature of MS-Nylon reached 42.29 °C after exposure to sunlight (illuminance of 88.5 × 103 LUX). Following exposure to incandescent (200 W) and infrared (375 W) lamps, MS-Nylon temperatures reached 49.45 °C and 90.00 °C respectively. Notably, nylon's inherent mechanical and bulletproof properties remained nearly unchanged. This work provides valuable insights for the design of next generation multifunctional protective equipment.
