多晶形γ-CuI晶体的制备与导电性能表征
Preparation and Conductivity Characterization of γ-CuI Crystal with Different Morphologies
摘要
Abstract
The γ-CuI crystals with different morphologies were prepared using crude iodine and CuSO4 as raw material, N2H4 ·H2O as reducing agent by liquid phase method and micro-emulsion technique respectively. The effect of liquid phase method and micro-emulsion technique conditions on the microstructure of γ-CuI crystals were studied by XRD and SEM techniques, and the influence of different morphologies on the conductivity of γ-CuI crystal was also analyzed. The results indicated that γ-CuI crystals with nano spherical and triangular pyramidal shapes were prepared respectively by using the liquid phase method, at 500 r/min for 30 min, PEG-6000 and citric acid as surfactants respectively. The γ-Cul crystal with hexagon shape was synthesized from the CuSO4 and NH4I solution prepared by controlling the CTAB: n-pentanol: cyclohexane: water (volume ratio) of 3:3:7:10 respectively, at 500 r/min for 2 h. Different morphologies and crystal sizes had great impact on the conductivity of γ-CuI, and the γ-CuI crystal with nano spherical shape has the lowest conductivity of 4. 9 Ω·cm.关键词
