Abstract
Certain aspects of the disclosure concern a device including a nozzle configured to receive a heated polymer solution from a reservoir and a power supply configured to generate an electrostatic field between a tip portion of the nozzle and a substrate so as to draw a charged jet of the heated polymer solution out of the tip portion of the nozzle toward a substrate situated at an operating distance from the tip portion of the nozzle and form a polymer fiber on the substrate. The heated polymer solution is at an operating temperature that is greater than or equal to 40° C.
