静电纺丝制备荧光导电双功能复合纳米纤维及其表征

采用静电纺丝技术将导电聚苯胺(PANI)和铕/铽稀土配合物掺杂到高分子基质聚乙烯吡咯烷酮(PVP)中,制备出荧光导电复合纳米纤维。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复合纳米纤维的性能进行分析,结果显示,在270nm紫外光激发下,铕系列与铽系列复合纳米纤维分别发出红光和绿光。同时,复合纳米纤维的电导率可以达到1.18×10~(-6) S/cm,两种复合纳米纤维同时具有优异的荧光性能及良好的导电功能。

Preparation and Characterization of Luminescence Electrical Bifunctional Composite Nanofibers via Electrospinning Technique

Composite nanofibers of Eu or Tb complex/polyaniline (PANI)/polyvinylpyrrolidone (PVP)composite in which rare earth complex and PANI act as model luminescence conducting materials,PVP acts as a supporting material,were successfully prepared via electrospinning as luminescence conducting materials.The properties of the novel luminescence conducting fiber were characterized by Scanning Electron Microscope (SEM),broadband dielectric spectrometer,fluorospectrophotometer (FL).Results suggested that under the excitation of 270 nm ultraviolet,Eu2 (2,6-pdc)3 (phen)2/PANI/PVP composite nanofiber emitted the predominant emission peak at 615 nm,Tb2 (2,6-pdc) 3 (phen) 2/PANI/PVP composite nanofiber emitted the predominant emission peak at 544 nm.The electric conductivity of the composite nanofibers reached 1.18 × 10-6 S/cm in high frequency electric field.The composite nanofibers had good conducting properties and excellent luminescent property.
