Electrospun polyimide (PI) nanofibers possessed high tensile strength (δ), but the breaking load (BL) is very small. It is also a challenge to prepare electrospun PI microfibers from the PAA precursor in high boiling point solvents. In this work, PI microfibers with diameter more than 2μm were prepared from their PAA-salt in water mixed with low boiling point solvent, such as ethanol. The single electrospun...
Polytetrafluoroethylene (PTFE) porous membranes are widely used for high-temperature filtrations. However, high quality PTFE membranes with excellent mechanical properties and thermal stabilities by electrospinning are still highly required. Polyamide-imide (PAI) is a high performance polymer with a combination of properties from polyamides and polyimides, such as high strength and thermal stability...
