Phys.org  May 17, 2023 Researchers in the UK have developed antimicrobial surface film based on sustainable micro fibrillated cellulose. The porosity, and microstructure of the film can be modulated by the formulations and the coating process. They observed a threefold reduction in water contact angles and accelerated water evaporation kinetics on the cellulose film (more than 50% faster than that on a flat glass surface). It exhibited a rapid inactivation effect against SARS-CoV-2 in 5 minutes, following deposition of virus-loaded droplets, and an exceptional ability to reduce contact transfer of liquid, e.g., respiratory droplets, to surfaces such as an artificial […]
