The most common route for transmission of infectious diseases is by indirect contact with surfaces contaminated with infectious droplets produced by human coughing, sneezing or talking. This work report a smart antimicrobial coating prepared from polymer-encapsulated chlorine dioxide (ClO2). The ClO2 was encapsulated by water-in-oil-in-water (w/o/w) double emulsion which consists of dispersed oily globules containing smaller aqueous droplets.   Touch and infectious droplets can trigger an increased release of the biocides at the sites of contamination, resulting in rapid disinfection. Low concentration copper (500ppm) and ascorbic acid (100ppm) were added to provide �contact-killing� property to coating. The desinged coating is effective against the DNA virus�adenovirus. A greater than 96.02% virucidal reduction activity was obtained in a short contact time of 1 min, and over 97.21 % and 98.92 % were obtained in the contact time of 3 min and 5 min, respectively.
