Eu(TTA)3(TPPO)2/PANI/PVP荧光导电双功能复合纳米纤维的合成及性能表征

摘要

Eu complexes were synthesized by linking TTA and TPPO as ligand up to Eu3+ as functional light-emitting group.Then, ultrafine composite fibers Eu(TTA)3(TPPO)2/PANI/PVP, in which Eu complex and PANI act as model luminescence and conducting materials respectively and PVP acts as a supporting material, were successfully prepared via electro-spinning as luminescence and electrical conduction materials.The properties of the novel luminescence conducting fiber were characterized by scanning electron microscope (SEM), broadband dielectric spectrometer, fluorospectrophotometer (FL).The composite nanofibers have good conducting properties and excellent luminescent property.%以2-噻吩甲酰三氟丙酮(TTA)为第一配体,三苯基氧磷(TPPO)为第二配体,通过与稀土铕离子进行配位,制备Eu(TTA)3(TPPO)2发红光的配合物;同时采用静电纺丝技术以聚乙烯吡咯烷酮(PVP)为载体基质,与樟脑磺酸(CSA)掺杂的导电聚苯胺(PANI)及荧光配合物Eu(TTA)3(TPPO)2制备出了一种新型的荧光导电纳米纤维Eu(TTA)3(TPPO)2/PANI/PVP.用扫描电镜(SEM)、荧光光谱仪(FL) 、宽频介电松驰谱仪对荧光导电纳米纤维的性能进行分析.结果显示,荧光导电纳米纤维具有优异的荧光性能及良好的导电功能.
