γ辐照二茂铁酰腙配位聚合物的介电性能研究

Studies on dielectric properties of ferrocenylhydrazone coordinated polymers irradiated by γ-rays

合成了三种二茂铁二甲酰腙金属(Cu、Co、Ni)配位聚合物,(PZM),研究了大剂量60Coγ辐照对配位聚合物的微波介电性能及温度–介电性能的关系,结果表明,随辐照剂量的增加及配位金属Cu、Co、Ni的顺序,配位聚合物的介电参数(ε′,tgδ)增加,但其升温–降温为不可逆曲线。另外,用红外差谱及电镜(SEM)探讨了辐照前后配位聚合物的微波化学结构变化及形貌。研究表明,这类配位聚合物有可能发展成有潜在微波通信应用的光、电、磁性多功能高分子材料。

The three ferrocenylhydrazone coordinated metal polymers were synthesized （PZM）. The effect of the 60Co γ irradiation on microwave dielectric properties and their temperature-dielectric properties were studies. It has been found that the dielectric parameters （ε′, tgδ） of coordinated polymers increase along with the absorbed doses and coordinated metals in order Cu, Co, Ni, However, the dependent curves of dielectric parameters on arise-down temperature are universal. On the other hand, the small changes in chemical structure before and after irradiation were confirmed by IR differential spectrometry and SEM. It is possible to make such coordinated polymers as a multifunctional polymeric material with optical, electric and magnetic properties, which may be potentially used in microwave communication.
