COVID-19 is affecting 216 countries and territories around the world. The issues of hygiene to defend against germs and viruses has significantly risen. Antiviral/antimicrobial coatings may be applied to a surface that has a chemical compound which is toxic to microorganism. We developed multi-functionalized polyurethane (PU) coating for surface’s durability, anti-biofouling, and biocidal effect. We synthesized perfluoro-isocyanate (F-NCO) containing of an umbrella-like structure for anti-fouling of airborne infectious particles. The PU-coated fabric had an improved aerosol protection performance without changing its air and moisture permeability. Secondly, we prepared quaternary ammonium alkyl chain-isocyanate (QAC-NCO) for biocidal effect. This coating contains QCA as killer of bacteria and urethane bond for durability on the outside and inside. Therefore, it has a high potential of realizing good performance by applying it to many fields where urethane coating is used. |
