Abstract

The coating effect of fine copper powder in situ polymerization is discussed in this paper. A certain amount of aniline hydrochloride is taken and dissolved in 20 ml deionized water. Appropriate amount of copper is added to it and stirred with ultrasounds for 10 min to form suspension; then adding ammonium persulfate and hydrogen peroxide through constant-pressure titration funnel to the mixed solution of copper/aniline hydrochloride suspension reaction under the condition of the ice bath for 4 h and after centrifugal, filtration, washing, collect the resulting product and dry it under the temperature of 80 °C for 2 h. Transform infrared spectroscopy analyzer is used for analyzing, and field emission scanning electron microscopy is employed for product observation. The result shows that when 0.45 ml hydrogen peroxide and 0.35 g aniline hydrochloride are added, copper surface coating material gives the best performance in terms of both density and uniformity.
