Perhydrolase S54V (AcT) effectively catalyzes the perhydrolysis of propylene glycol diacetate (PGD) to generate peracetic acid (PAA). PAA is a potent oxidant used for sanitization and disinfection, with broad effectiveness against bacteria, yeasts, fungi, and spores. In this study, active and stable composites are developed by incorporating AcT–carbon nanotube conjugates into polymer and latex‐based paint. At a conjugate loading of 0.16% (w/v), the composite generated 11 m M PAA in 20 min, capable of killing more than 99% spores initially charged at 10 6 colony‐forming units per milliliter.
