Abstract
In this study a non-conventional electrospinning technique was designed for production of high bulky polyacrylonitrile
(PAN) nanofiber mats. Optimum nanofiber mats are achieved with 15 wt% solution of PAN in DMF. Such mats result in a bulk porosity which is as high as 99.9 and density as low as 0.84x10-3
g/cm2 . Effect of nanofiber mats porosity on the
air permeability and moisture transfer was investigated. Based on the results, high bulky nanofiber mats possess high moisture transfer. Experimental data reveals that with a slightly decrease in the bulk porosity, air permeability decreased
noticeably, while moisture transfer changed slightly.
Keywords: Polyacrylonitril, moisture transfer, Bulk porosity, Air permeability.
