Abstract

Polyetherimide (PEI) and poly(vinylidene fluoride) (PVdF) blend web was prepared by electrospinning technique. In order to improve low mechanical properties, post processes like hot-pressing and heat-stretching were employed, and a study on the effects of post processes on their mechanical properties was performed. To confirm the physical properties of the web, scanning electron microscopy and tensile measuring instrument were used. The mechanical strength of webs pressed in the ratios of 1/2, 1/3, 1/4 and 1/5 at 180 ^°C were improved four-to-five times compared to pristine webs. Also they showed an additional increase by 2-8 MPa, by heat-stretching 30 to 40% at 220°C.
