Supplementary Video S1 for “Salt-templated hierarchical porous activated-carbon films for efficient and regenerable single-pass indoor VOC purification”

Supplementary Video S1 demonstrates the mechanical stability of STF#3 (activated-carbon/NaCl mass ratio = 3:3) after more than 25 adsorption–regeneration cycles. The film maintains good structural integrity during repeated bending, with no obvious cracking, delamination, or particle shedding observed.
