Abstract
To improve the stability of fine copper powder, it was pretreated by benzotriazole first. Then ammonium persulfate was dripped into treated powder/aniline suspension to produce polyaniline/copper composite. Detected by field emission scanning electron microscope, transmission electron microscope, X-ray diffractometer and FT-IR spectroscopy, it has been proved that the composite has core-shell structure, its core is of copper particles, and its shell is interlaced with reduced half-oxidized polyaniline fibers. Tested by thermogravimetric analyzer, the composite had four stages of degradation in nitrogen and was more stable than copper powder in air.
