碘掺杂聚二茂铁-茴香醛的合成与表征

Synthesis and Characterization of Iodine Doped Polyferrocene-anisaldehydes

采用液相掺杂法合成了碘掺杂的聚二茂铁茴香醛,通过红外光谱和热分析(TGA、DSC)对合成产物进行了分析表征,探讨了掺杂前后聚二茂铁茴香醛的红外光谱和热稳定性的变化.结果表明碘掺杂后聚二茂铁茴香醛的红外光谱与本体聚二茂铁茴香醛的红外光谱相比,虽然主峰位置没有明显的变化,但吸收峰合并,谱峰数目大大减少,吸收强度大大减弱,随着掺入的碘量的增加,吸收率有所增加;碘掺杂聚二茂铁茴香醛的热稳定性与聚二茂铁茴香醛相比,低温耐热性能下降,而高温(300℃以上)耐热性却无明显的影响.

Iodine doped polyferrocene-anisaldehydes were synthesized by liquid phase method. The synthesized polymers were characterized by infrared spectra (IR) and thermal analysis (TGA & DSC); and the differences of infrared spectra (IR) and thermal stability of polyferrocene-anisaldehydes between before and after adulteration were discussed too. The results reveal that the infrared spectra peaks of iodine doped polyferrocene-anisaldehydes amalgamate, the numbers of peaks lessen greatly, and the absorption strength lessens greatly too, while the absorption ratio increases with increase of doped iodine. Compared with polyferrocene-anisaldehyde, the thermal stability of iodine-doped polymer lower down at low temperatures, but has no obvious change at higher temperatures (above 300 ℃).
