Synthesis and characterization of nickel aluminum hydrotalcites and study on fabric memory effect

WANG Jun1,2,LIU Yan-feng2,ZHANG Yan2,LIU Qi2,LI Song-nan2,JIANG Zhao-hua1 (1.College of Chemical Engineering,Harbin Institute of Technology,Harbin 150001,China;2.School of Material Science and Chemical Engineering,Harbin Engineering University,Harbin 150001,China)  
A series of nickel aluminum hydrotalcites were synthesized by hydrothermal methods with urea used as the precipitant,and a further exploration on the synthesis conditions was carried out accordingly.Experiments on restoration of calcined samples were also conducted.The prepared samples were characterized in detail by XRD,FT-IR,TEM,and BET techniques.Under the conditions of the recovery experiment,Ni-Al hydrotalcites samples that were calcined at temperatures ranging from 200 ℃ to 350 ℃ could be restored completely.The structure of LDO samples could not be completely restored if the calcination temperature rose further to a structural collapse temperature.
