以粗碘和硫酸铜为原料,水合肼为还原剂,利用液相法和微乳液法合成了不同晶形γ-CuI晶体.采用XRD和SEM研究了液相法和微乳液工艺技术条件对合成γ-CuI微观结构的影响,分析了具有不同微观结构γ-CuI对其导电性能的影响.结果表明,分别以聚乙二醇(PEG-6000)和柠檬酸为表面活性剂,采用液相法常温下500 r/min反应30 min可制备出纳米球形和三角锥形γ-CuI.按CTAB-正戊醇-环己烷-水配比3∶3∶7∶10分别配制硫酸铜和碘化铵微乳液,常温下500 r/min反应2h可制备出六边形薄片状γ-CuI.不同微观形貌和粒径分布对γ-CuI产品电导率具有较大的影响.纳米球形γ-CuI电导率最小,为4.9 Ω·cm.
