Abstract
The present paper aims to study the preparation of polyaniline nanofibers through simple interfacial polymerization. Ammonium persulfate, hydrochloric acid and chloroform were used as oxidant, dopant and organic solvent respectively. Field Emission Scanning Electron Microscopy (FESEM), X-ray diffraction and Fourier Transform Infrared Spectroscopy (FTIR) techniques were used to analyze the product. FESEM results show that polyaniline has nano-fiber morphology. XRD results show the crystalline properties of polyaniline nanofiber, and FTIR results confirmed the formation of polyaniline in different monomer/oxidant molar ratios. This study provides a better understanding on the synthesis of uniform polyaniline nanofibers through interfacial polymerization.
Highlights
Conductive polymers belong to an interesting group of polymers, which have unique electrical, electrochemical and optical properties [1,2]
This paper aims to study the production of polyaniline nanofibers at different aniline/oxidant ratios through simple interfacial polymerization
It has been found that different aniline/APS molar ratios affected the uniformity and morphology of polyaniline
Summary
Conductive polymers belong to an interesting group of polymers, which have unique electrical, electrochemical and optical properties [1,2]. They could be used in different applications such as hydrogen storages [3,4] sensors [5], solar cells [6], antistatic coatings [7], diodes [8] and anticorrosive. Polyaniline and its derivatives are synthesized through two general routes: (a) electrochemical; and (b) chemical methods [11]. The aniline is polymerized in water based solution in the presence of oxidant and dopant. The synthesized polyaniline appears in the form of irregular granular particles
