A nanohybrid ethanol emitter (EE) was developed to reduce the risk of bacterial and virus infection via the surface route. The porous EE structure generated from physical aggregation of ethyl cellulose (EC) and sodium stearate (NaSt) exhibited a high loading capacity of ethanol of up to 73 wt %, controlled-release performance for longer than 11 h, and high mechanical strength (>20 N). After disinfection tests with contaminated substrate surfaces in a closed box at 25 °C for 6 h, EE showed high potential antimicrobial properties against both bacteria and viruses for more than 99.90%. Hence, it can be applied as an effective disinfectant for daily contaminated surfaces frequently touched such as banknotes, coils, key cards, and cloth masks in a closed container system. Moreover, a simple and low-cost process using eco-friendly chemicals for EE preparation offers high potential for large-scale production in the industry.
