Polypyrrole/Poly(acrylonitrile‐co‐butyl acrylate) Composite

Abstract

Poly(acrylonitrile-co-butyl acrylate) [P(AN-co-BuA)] was synthesized from acrylonitrile (AN) 95% and butyl acrylate (BuA) 5%-molar ratios-by free-radical polymerization in aqueous media, using ceric ammonium nitrate as an initiator. Pyrrole was oxidatively polymerized in dimethylformamide in the presence of P(AN-co-BuA) matrix to produce polypyrrole (PPy) composites. Composite thin films were produced by solution casting onto smooth glass surfaces. Scanning electron microscopy and Fourier transform infrared-attenuated total reflectance analysis of thin films revealed the presence of PPy in the composite structure. Electrical impedance measurements were conducted to reveal the electrical conductivity change due to increasing PPy content. Enhancing the flexibility of PPy structures, as a composite film composed of PPy, could find substantial utility in the application of PPy products. BuA in a copolymer structure with AN improved the mechanical properties of the resulting copolymer by compensating the mechanical disadvantages of PPy. The

Characterization of polyacrylonitrile, poly(acrylonitrile‐co‐vinyl acetate), and poly(acrylonitrile‐co‐itaconic acid) based activated carbon nanofibers

“…The flow rate of the feed was set at 1 mL/h, and the applied voltage between the tip and collector was set to 16 kV, with a tip‐to‐collector distance of 16 cm. The fibers were collected on the aluminum foil in the form of nonwoven fabric . A schematic illustration of the experimental apparatus is shown in Figure .…”

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

“…Copolymerization of AN gives the chance of distruption of strong dipole interactions, increasing decomposition temperature and decreasing high melting point of the polymer [6]. Acrylates (methyl acrylate and butyl acrylate), vinyl acetate, ketones, alcohols, acrylic acid and itaconic acid (IA) are among the widely used comonomers [7][8][9][10][11][12]. Polymerization of AN with vinylacetate was studied by Çetiner et al [6] and it was observed that by addition of vinylacetate to AN, the solubility of the polymer in spinning solutions increased.…”

“…Sen and Sarac [13] selected IA as a comonomer for the production of poly(acrylonitrile-co-itaconic acid) (P(AN-co-IA)) polymer, and they showed that using higher IA ratios in polymerization step let to decreased decomposition temperature of the obtained polymer. In a study, Unsal et al [10] copolymerized AN with butylacrylate and pyrrole; they showed that by incorporation of butylacrylate to the system, the mechanical properties of the resulting polymer improved. Copolymerization of P(AN-co-IA)-polypyrrole was achieved by Arman and Sarac [14] via emulsion polymerization for the synthesis of AN and vinylacetate in order to investigate the morphology of the nanocomposites.…”

Synthesis and Electrochemical Evaluation of Conductive Polyacrylamide Nanocomposite Hydrogels

“…They are also suitable for a wide range of applications such as supercapacitors, dye‐sensitized solar cells, fuel cells, rechargeable lithium batteries, sensors, and drug‐carrying material because of colloidal stability, low cost, and ease of preparation . Hydrogel conductivity can be improved by the addition of carbon‐based particles and using conducting organic comonomers . Graphene among carbon‐based materials seems to have exceptional thermal, mechanical, and electrical properties …”
