microfiber webs produced by different dopants and solvents (original) (raw)

Journal of Industrial Textiles, 2015

Abstract

In the present study, the effects of different dopants such as camphorsulfonic acid (CSA), dodecylbenzene sulfonic acid (DBSA) (70 wt% in isopropanol), and dodecylbenzene sulfonic acid sodium salt (DBSANa+), and different solvents such as N-methylpyrrolidone (NMP), and N,N-dimethylformamide (DMF) on the structure and properties of polyacrylonitrile (PAN)/polyaniline (PANI) composite nano/microfiber web produced by the electrospinning technique have been investigated and compared to each other. It has been observed that the nano/microfibers produced from NMP solvent generally had larger fiber diameters than the nano/microfibers produced from DMF, while the use of DBSANa+ resulted in the formation of larger diameters in comparison to other dopants. The use of NMP as the solvent resulted in higher breaking stress values for the reference samples and the composite samples, which contained CSA-doped PANI while the samples that contained DBSA(iso) and DBSANa+-doped PANI showed lower break...
