Yun Shen and George Washington University colleague Danmeng Shuai created a nanofiber filter that delivers a high voltage through a drop of polyvinylidene fluoride liquid to a spinning thread about 300 nanometers in diameter—about 167 times thinner than a human hair . This process created pores just a few micrometers in diameter on the nanofibers’ surface, helping them capture 99.9 percent of coronavirus aerosols.

Usoro mmepụta, nke a maara dị ka electrospinning, na-akwụ ụgwọ ọnụ ma nwee ike iji ya mee ihe nzacha nanofiber maka ngwá ọrụ nchedo onwe onye na usoro ntinye ikuku. Electrospinning na-ahapụkwa ụgwọ electrostatic na nanofibers, nke na-eme ka ikike ha nwee ike ijide aerosols, na nnukwu porosity ya na-eme ka ọ dịkwuo mfe iku ume mgbe ha na-etinye ihe nzacha electrospun nanofiber.

“Electrospinning technology can facilitate the design and manufacture of masks and air filters,” said Prof. Yun Shen. “Using electrospinning technology to develop new types of masks and air filters has good filtration performance, economic feasibility and scalability. Being able to meet the demand for masks and air filters in the field is very promising.”
