Abstract
Nowadays, nanofibers and nanoparticles have become the attraction of study for researchers. Due to the unique physical properties such as ultra-thin fiber diameter. The electrospinning manufacturing technique produces nanofibers that have potential applications in the electronic, biomedical, and filtration industries. Until today, plenty of polymers has been electrospun into nanofibers. Researchers are trying to find the finest nanofibers with excellent spinnability on electrospinning.This study's goal was to optimize the solution for polyamides on alternating current (AC) electrospinning. The polymers PA 6 and PA 6,12 have been chosen for the study. These polymers were dissolved in the mixture of formic acid and dichloromethane at a weight ratio of 1:1 with an increasing concentration of sulfuric acid. All the solutions were electrospun on the alternating and direct current electrospinning systems. The solubility and spinnability of polyamides were investigated. The scanning electron microscope was used for nanofiber diameter measurement. The solution parameters, such as surface tension, conductivity, and viscosity, were measured to see the impact of acid content on the mixture.All the prepared polyamide solutions were spun on both AC and DC electrospinning systems. The sulfuric acid concentration influences the spinnability, nanofiber diameter, and solution properties. AC and DC electrospun polyamide nanofibrous structures are different in terms of bulkiness or thickness.
