Scanning Electron Microscope (SEM) model FEI Quanta 400 with 500x and 2000x magnification were used for
fiber membrane morphology information. Studies performed in high vacuum mode and at a voltage of 20 kV.
Samples coated with a thin layer of gold using the SC 500 sputter coater model in vacuum surrounding around 0.1 -
0.5 torr in the presence of an inert gas (Argon). SEM observations were conducted on samples of the fiber
membrane
