Syringeless electrospinning is one of the needleless electrospinning methods, using several helically embedded conductive probes on a rotating cylinder instead of syringe and needle. It produces increase of nonwoven mat production rate and allows colloid electrospinning with large amount of filler compared to previous works. In this work, we use polymeric solution made of Polyacrylonitrile (PAN), Thermoplastic Polyurethane (TPU) and Polyvinylpyrrolidone (PVP), adding inorganic fillers such as TiO2, ZrO2, Silica particle and Metal organic framework (MOF). Particularly, MOF is used as catalyst for detoxification of nerve agent mimic, Diisopropyl fluorophosphate (DFP). By adding 2 times filler than polymer weight, functions of filler are introduced easily to electrospun nonwoven mat and mechanical and chemical properties are changed depending on added fillers, maintaining property of nonwoven mat like flexibility. |
