Abstract

Electrospinning is a method that uses electrical force to produce polymeric fibers with diameters ranging from nanometer to micrometer. Polystyrene (PS) fibers from the solution of Dimethylformamide (DMF) and different amounts of Silica Nanoparticles (SNP) (0-4% w) were electrospun under different environmental Temperature (25-45 ° C) and Relative Humidity (30-70%) conditions. An environmental chamber for changing and controlling the electrospinning environment conditions, i.e. Temperature and Relative Humidity, were constructed. An experimental design was made using different levels of Temperature, Relative Humidity. The morphology of the PS fibers was investigated using SEM images. The results showed that by increasing Temperature, Relative Humidity, and SNP, the morphology of PS fibers was changed from bead on to fine and beadless. Nano-porous electrospun fibers were evolved by varying the three parameters. It was seen that the density of nanopores in the surface of PS fibers was increased with increasing Relative Humidity, and decreased with increasing Temperature and SNP.
