Scientists have synthesized the material that is perfect for protection of respiratory organs, analytical research and other practical purposes. An almost weightless fabric made of nylon nanofibers with a diameter <15 nm beats any other similar materials in terms of filtering and optical properties. The material is lightweight (10-20 mg/m2), almost invisible (95% light transmission: more than that of a window glass), showing low resistance to airflow and efficient interception of <1 micrometer fine particulate matter.
Previously, the same team showed reducing fiber diameter from 200 nanometers down to 20 decreased filter resistance to airflow by 2/3s, and this effect could no longer be explain...
