Electrospun Fibres Covered Micro-structured Fibres for Air Filtering

摘要：

　　Air pollution was caused by toxic dust particles and bacteria floating in the air.Micro-/nano fibres with large surface areas are potentially used for air filtering in expectation of high filtering efficiency.Fine fibres made from centrifugal spinning of PVA,PAN and PS were investigated for air filtering in terms of fibres physical properties and morphologies.Rotating spinning showed competitive power in production yield.Porous fibre mats could filter particles which were larger than the pores in fibre mats.However, lower filtering efficiency of PM2.5(<85%) was observed in rotating spun fibres compared with electrospun fibres (>95%).Electrospun fibres covered rotating fibres showed higher filtering efficiency with competitive mechanical properties and low cost.
