Poly(acrylonitrile-co-itaconic acid)–poly(3,4-ethylenedioxythiophene) and poly(3-methoxythiophene) nanoparticles and nanofibres

Abstract

This work aimed to produce poly(acrylonitrile-co-itaconic acid) (P(AN-co-IA)) nanocomposites with poly(3,4ethylenedioxythiophene) (PEDOT) and poly(3-methoxythiophene) (PMOT). An anionic surfactant sodium dodecyl benzene sulphonate was used in emulsion polymerization for nanocomposite production. Incorporations of PEDOT and PMOT on the nanoparticles were characterized by scanning electron microscopy (SEM), atomic force microscopy, Fourier transform infrared-attenuated total reflectance spectroscopy and ultraviolet spectroscopy. These nanoparticles were blended with PAN and the blends were electrospun to produce P(AN-co-IA)-polythiophene-derivative-based nanofibres, and the obtained nanofibres were characterized by SEM and energy dispersive spectroscopy. In addition, electrochemical impedance studies conducted on nanofibres showed that PEDOT and PMOT in matrix polymer P(AN-co-IA) exhibited capacitive behaviour comparable to that of ITO-PET. Their capacitive behaviour changed with the amount of electroactive polymer.

Nanocomposite structures of polypyrrole derivatives and poly (acrylonitrile‐co‐itaconic acid) produced by in situ polymerization as carbon nanofiber precursor

“…P (AN‐co‐IA) nanocomposite was synthesized by emulsion polymerization as described in our previous study as it was briefly shown as a scheme in Figure …”

“…Characterization results revealed that changing amounts of NMPy has considerable effect on both dielectric properties and electromagnetic characteristics . Previously, morphological, spectroscopic, and electrochemical impedance studies were performed on P (AN‐co‐IA)/polythiophene nanocomposites and nanofibers obtained by electrospinning . Itaconic acid (IA) is among the comonomers preferred for generating nanocomposites with PAN since each monomer unit has two carboxylic groups leading to decrease of the melting and increase of the decomposition temperature of the copolymer .…”

Electrospun nanofibers of poly (acrylonitrile-co-itaconic acid)/silver and polyacrylonitrile/silver:In situpreparation, characterization, and antimicrobial activity

“…Synthesis of P(AN-co-IA) copolymer and PAN homopolymer P(AN-co-IA) copolymer was synthesized by emulsion polymerization utilizing water, SDBS and APS as dispersion medium, surfactant, and initiator, respectively. The polymerization was lasted for 3 h at 70 C and then stopped using ethanol and then cooled to room temperature as in previous studies [41][42][43]. The obtained emulsion latex was precipitated and washed with ethanol and water for five times.…”

“…Average diameter of the nanofibers was also determined using a special program, Image J. Figure 9 [43] shows SEM images of PAN and P(AN-co-IA) nanofibers along with their diameter distribution graphics. Figure 9 [43] shows that PAN and P(AN-co-IA) nanofibers are continuous, smooth, and fine with the average diameters of 120 and 132 nm, respectively.…”
