• The SiO₂ nanofiber membranes and MXene@c-MWCNT_6:4 as one unit layer (SMC₁) were bonded together with 5 wt% PVA solution.

• When the structural unit is increased to three layers, the resulting SMC₃ has an average electromagnetic interference SE_T of 55.4 dB and a low thermal conductivity of 0.062 W m⁻¹ K⁻¹.

• SMC_x exhibit stable electromagnetic interference shielding and excellent thermal insulation even in extreme heat and cold environment.
