Electrospinning of p-Aramid Fibers

Macromolecular Materials and Engineering, 2015
Electrospun poly (p-phenylene terephthalamide) (PPTA) fibers with diameters between 275 nm and 15 µm were obtained from anisotropic solutions, albeit that the spinning process was difficult to control. Key solution parameters like conductivity, surface tension, and viscosity were used to compare the spinnability of these anisotropic solutions with ...
