Polyacrylonitrile/polyaniline composite nanofiber webs with electrostatic discharge properties

Abstract

In this study, composite nanofibers of polyacrylonitrile (PAN) and polyaniline (PANI) were successfully produced by electrospinning technique and the effects of different dopants such as camphorsulfonic acid (CSA), dodecylbenzene sulfonic acid (DBSA) and dodecylbenzene sulfonic acid sodium salt (DBSANa þ ), and different solvents such as dimethylsulfoxide (DMSO) and N,N 0 -dimethylformamide (DMF) on the properties of PAN/PANI composite nanofiber webs have been investigated. It has been observed that nanofibers produced from DMSO generally had larger fiber diameters and higher breaking strength than nanofibers produced from DMF. CSA could dope better than DBSA(iso) and DBSANa þ . CSA resulted in the highest conductivity when DMSO was used while it resulted in lower conductivity in DMF. The insulator PAN became a semiconductive material with the incorporation of CSA-doped PANI. The highest electrical conductivity obtained was 10 À6 S/cm which is in the range suitable for electrostatic discharge applications.

Guanine oxidation signal enhancement in single strand DNA with polyacrylonitrile/polyaniline (PAN/PAni) hybrid nanofibers

“…27 In this regards, they produced continuous pure PAni fiber by doping (1)-camphor-10-sulfonic acid and coaxial electrospinning with poly(methyl methacrylate) (PMMA) and following removal of PMMA shell polymer. Polyacrylonitrile/ polyaniline (PAN/PAni) composite NFs were produced by Kizildag et al 28 using different solvent and dopant materials, and NF web electrostatic discharge properties were investigated. NF diameters and fiber breaking strengths were varied depending on solvent and doping materials used.…”

Recent progress on nanostructured conducting polymers and composites: synthesis, application and future aspects

“…The significant improvement of the antistatic property of the nanocomposites is mainly due to the conductive network formed inside composites. Recently, many other nanocomposites have been synthesized for antistatic application, such as graphene-based PANI nanocomposites [404], MWCNT and silver nanoparticle decorated polypyrrole in epoxy matrix [405], and polyacrylonitrile/PANI composite nanofiber webs [406].…”

Synthesis of a novel electrode material containing phytic acid-polyaniline nanofibers for simultaneous determination of cadmium and lead ions

“…Previous studies on the conductivity of PANI have proved that the effect of dopant, e.g. the acidity of the dopant and the molecular size of the counter ions, is significant [45,46]. Moreover, the organic acid doped conducting polymer often gives better conductivity than the pure inorganic acid doped conducting polymer due to the so-called secondary doping [47].…”
