Facile synthesis of polyaniline nanofibers in supercritical CO2 with high yield

Facile synthesis of polyaniline nanofibers in supercritical CO2 with high yield Interfacial polymerization of aniline in a mixture of supercritical CO2 and water has been used to produce polyaniline (PANI) nanofibers. Ammonium persulfate was used as oxidizing agent. No surfactant or template was used. The diameters of the PANI nanofibers were approximately 60–80 nm and the lengths were up to several micrometers. Scanning electron microscopy, Fourier transform infrared spectroscopy (FTIR), and XRD analysis were used to characterize the morphology and structure of the as-synthesized product. FTIR results revealed that the synthesized nanofibers were in the highly conductive emeraldine state. The process is environmentally friendly and has a yield of approximately 80 %. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Research on Chemical Intermediates Springer Journals

Abstract

Interfacial polymerization of aniline in a mixture of supercritical CO2 and water has been used to produce polyaniline (PANI) nanofibers. Ammonium persulfate was used as oxidizing agent. No surfactant or template was used. The diameters of the PANI nanofibers were approximately 60–80 nm and the lengths were up to several micrometers. Scanning electron microscopy, Fourier transform infrared spectroscopy (FTIR), and XRD analysis were used to characterize the morphology and structure of the as-synthesized product. FTIR results revealed that the synthesized nanofibers were in the highly conductive emeraldine state. The process is environmentally friendly and has a yield of approximately 80 %.
