| Abstract: | The samarium electropolyurushiol coordination polymer was obtained from samarium chloride and electropolyurushiol in isopropyl alcohol solution.The coordination polymer was characterized by FT IR,Fluorescence spectrum,XPS,DMTA,DTA TG and AES,and its composition and structure were determined.Each Sm 3+ ion is coordinated by hydroxyls from three units in EPU molecule.It showed that there is a certain coordination between Sm 3+ and EPU in the coordination polymer,thus crosslinking was formed.Therefore the polymer with Sm 3+ content as high as 13 18% is insoluble in the organic solvents.Its electric resistance is 9 6×10 10 Ω (that of EPU was 7 9×10 10 Ω).Its glass transition temperature and heat resistance are considerably greater than those of EPU. |
