Preparation and study of some physical properties of (Polystyrene Ethel vinyl acetate)‎ blend nanofibers

Abstract EN

This search aims to fabricate immiscible nanofibers (Polystyrene/Ethyl phenyl acetate) blends with different average porous for different applications by electrospinning technique.

PS and EVA were mixed by (50/50) to prepare 0.1 (w/v) con.%, each polymer dissolved in (Tetra hydro furan ).

Resulting nanofibers morphology was studied by Atomic force microscopy (AFM) and high optical resolution microscope (HORM) , Contact angle between the water and the surface of nanofibers by contact angle analyzer also studied for (hydrophilic or hydrophopic behavior ).

FTIR test for checking the emergence or not of new bonds in the nanofibers blend was performed.

AFM Results show that the prepared blends of (PS+EVA) have homogenous needle structures (nanofibers) at three dimensions , while the results of (HORM) shows the nonwoven structures contain intermediates pours structure , Contact angle results show that decrease of the contact angle after adding the EVA polymer to PS, and this refers to the (EVA/PS) nanofibers blends have hydrophilic behavior.
