摘要:In this talk, the current research status on the recent developed new functions of conducting polymer polyaniline (PANI) in the applications including heavy metal adsorbents,giant magnetoresistance (GMR) sensors, coupling agents, and flame retardants have beencritically reviewed. The magnetite/polyaniline nanocomposites synthesized by surface initiated polymerization method exhibited a superior Cr(VI) removal performance within the whole pH range and the presence o f Fe3O4 core favored there cycle of the magnetite/polyaniline nanocomposites. Besides, we studied the effects of dopant, oxidant and dose of oxidants on the GMR of pure PANI. Specifically, 53% of GMR value at room temperature was obtained in the p-toluene sulfonic acid (PTSA) doped pure PANI synthesized by ammonium persulfate (APS). A room temperature GMR value of 65.5% was observed in the phosphoric acid (H3PO4) doped pure PANI oxidized by APS. Meanwhile, we applied the PANI to improve the nanofiller dispersion and interfacial interaction by serving as coupling agent between nanofillers and epoxy resin. The tensile strength of epoxy nanocomposites was hugely increased up to 85% compared with pure epoxy resin. Finally, after introduction of phosphoric acid doped PANI into silica/epoxy nanocomposites, the heat release rate of epoxy was obviously decreased, exhibiting an improved flame retardant property.
