中文摘要：
合成、表征了氯化胆碱/尿素型低温熔盐,以此为溶剂研究了氧化锌在其中的溶解过程、离子组成、以及锌的电化学还原反应规律,分析了温度、电位、离子浓度对锌沉积物的形貌、晶型和纯度的影响。研究表明,当溶液中Zn（Ⅱ）的浓度为0.3~0.5mol/L时,可在313.2~343.2K、-0.3~-0.6V下获得平整、致密、均一的锌沉积层,此时其在铜基体上沿着（002）晶面优先生长。该技术不仅提高了锌镀层的质量和纯度,也有望扩展到锌精炼、锌合金和功能锌材料的制备等领域。
英文摘要：
Novel low-temperature molten salts forming between choline chloride and urea were synthesized and characterized. Dissolution process of zinc oxide, relative ionic structure in choline chloride/urea, and electrochemical reduction reaction rule of zinc were investigated. The effects of temperature, potential and Zn（ Ⅱ ） concentration on surface morphology, crystal pattern and purity of zinc deposits were analyzed. The results show that smooth, dense and homogeneous zinc coatings with preferred crystallographic orientation of （002） on copper substrates can be obtained under the conditions including Zn （Ⅱ） concentration of 0. 3~0. 5 mol/L, temperature of 313.2~343.2 K, and potential of --0. 3~--0.6 V. Not only improving quality and purity of zinc coatings, this new technique also can be applied in zinc electrorefining, production of zinc alloys and functional materials.
