Researchers at #UTokyo_IIS develop a filter that effectively captures small particles without restricting air flow
Researchers from the Institute of Industrial Science, The University of Tokyo have developed a filter that effectively blocks small particles while allowing unrestricted air flow. Such a filter is attractive for use in face masks that are highly effective while maintaining wearer comfort. The filter is constructed from nanosheets consisting of a mesh containing tiny pores supported on a nanofiber-coated fabric with larger pores. This hierarchical pore structure blocks nanoparticles while allowing air flow.
