Abstract

The porosity of fibers electrospun from polystyrene (PS)/dimethylformamide (DMF) solution at environmental
conditions of 40 ◦C and 60% relative humidity is characterized by three principally different
methods, i.e. thermoporometry, nitrogen adsorption/desorption (according to BET, DFT and BJH theories)
and density measurements. Different aspects of porosity including mean pore radius, specific surface area
and total pore volume of electrospun fibers are evaluated. Results demonstrate that each of these aspects
can be best described by one of the investigated techniques. In other words the mentioned methods act
as complementary approaches to make known the characteristic of porous electrospun fibers.
