Formation of Polyarylate Nanofibers Using Melt‐Electrospinning for Potential Vibration Damping Application

ABSTRACT Nanofibers have emerged as crucial materials in the modern scientific world, with applications spanning a wide range of disciplines. With the growing demand for electrospinning technology, understanding the unique attributes of materials like polyarylate fibers has become crucial. This study developed and analyzed polyarylate ultrafine fibers using Vectra, with a specific focus on a three‐layer arrangement, ethylene‐vinyl alcohol copolymer (EVOH)/Vectra/EVOH. The effect of variation of thin‐film thickness of both EVOH and Vectra were studies along with the effects of solution flow rate on the fiber diameters. Ultrafine polyarylate fibers were successfully prepared, reaching a remarkable diameter of 0.31 µm, from a three‐layer film EVOH/Vectra/EVOH ratio with 150/10/150 and film feed rate of 1 mm/min. Notably, the study revealed a significant correlation between fiber diameter and vibration damping efficiency. Decreased fiber diameter not only demonstrated the successful fabrication of ultrafine polyarylate fibers but also exhibited enhanced vibration damping properties.
