Multi-layer electrospun nanofiber mats with chemical agent sensor function

Electrospun nanofiber web were developed to examine the feasibility of developing chemical and warfare agent detector textile materials. Some parameters of nanofiber mats, including the polymer type, time of electrospinning and the polymer solution concentration, were designed to change and pH detection properties of specimens were compared. Multi-layered electrospun nanofiber mats equipped with pH sensitive dyes showed good performance in pH detecting property that opens up new possibilities for using in the protective garment application as the chemical and warfare agent detectors. It was also found that the developed electrospun fibers due to their porous structure and fiber diameter distribution are stable for chemical warfare detection in the form of gas.
