摘　　要：以Mn Cl2和CO(NH2)2为反应前驱物在溴苯/水溶液界面上、超重力为1000/g的条件下采用水热方法合成片状Mn CO3薄膜,研究了前驱物浓度、温度、超重力大小和反应时间对Mn CO3薄膜形成的影响。采用SEM、XRD、FT-IR对样品的形貌和物相进行表征。结果发现较低的温度和高重力场条件有利于薄膜状Mn CO3薄膜的形成。形成Mn CO3薄膜的最优条件是在1000/g超重力场、溴苯/水溶液体系、120℃条件下水热反应30 min,在该条件下制备得到的Mn CO3薄膜光滑致密,并且具有金属光泽。A flake-like MnCO3 film has been successfully synthesised by the hydrothermal method, with high gravity field 1000/g in the aqueous solution-bromobenzene system,which used MnCl2 and CO（NH2）2 as precursor . The effect of the precursor concentration,temperature,the relative centrifugal field and reaction time on the formation of flake-like MnCO3 film were investigated. The resultant samples were characterized by scanning electron microscopy （SEM）, powder X-ray diffraction （XRD） and IR spectra. The results reveal that lower temperature and higher gravity field are favourable for the formation of flake-like MnCO3 film. The optimum condition is in the aqueous solution/bromobenzene system under 1000/g relative centrifugal field at the temperature of 120℃. The flake-like MnCO3 prepared under the conditions is of smooth outside surface and metallic luster.
