A Review on the Fabrication of Electrospun Polymer Electrolyte Membrane for Direct Methanol Fuel Cell

Table 5

Desired properties for some desired applications of electrospun nanofiber.

Application	Tissue engineering	Filter media	Fuel cell
Material	Poly (D,L-lactide-co-glycolide) (PLGA)	Polyacrylonitrile (PAN)	Sulfonated poly (arylene ether sulfone) (sPAES)
Morphology	Nonwoven,; highly porous	Solution with low mass fraction produces beads on fiber and high mass fraction produces smooth and uniform fiber	Clear nanofiber with uniform dense Norland Optical Adhesive (NOA) 63 polymer filled completely the interfiber void of nanofiber
Average diameter; (nm)	500–800	270–400	40–160 (at first stage) can increase to 0.73–165 (after compaction/embedded)
Mechanical strength	Higher along with decrease in diameter of fiber	NA	Increased for embedded nanofibers
Controlled parameter	Voltage of 18 kV, 20 mL glass syringe, 18 G needle, 20 cm needle to collector distance, copper collecting plate	5 cm needle to collector distance, humidity controlled chamber in pure N2, 25% relative humidity, voltage of 3–10 kV, 400 m inner diameter capillary	NA; rotating drum (horizontally)
