Preparation and properties of 8‐hydroxyquinoline aluminum quinoline/polyaniline core–shell composite

Polyaniline (PANI) as an excellent conducting polymer material has been used to synthesize 8‐hydroxyquinoline aluminum quinoline/polyaniline (Alq₃/PANI) composites with core‐shell structure which is expected to form ultra‐conjugated system between core/shell and be used as organic electronic material. Alq₃ was coated by sodium dodecyl benzene sulfonate doped PANI via in situ polymerization of aniline on the surface of Alq₃. The morphology, structure crystallinity, and thermal stability of synthesized composite were characterized by Fourier transform infrared spectroscopy, X‐ray diffraction, scanning electron microscopy, and thermal gravimetric analysis. Results indicated that the composite is core‐shell structure and exhibits good thermal stability. Conductivity of composite was investigated and showed that Alq₃ as core in composite which improved the conductivity of pristine PANI, indicating that electronic interactive effect was formed between core and shell.
