摘要

采用静电纺丝法分别制备了聚4-乙烯基吡啶(P4-VP)纳米纤维和荧光聚4-乙烯基吡啶/卟啉(P4-VP/TPPA)纳米纤维。的浓度的影响P4-VP /二甲基甲酰胺(DMF)电纺的解决方案P4-VP形态的纳米纤维研究和发现P4-VP / DMF的纳米纤维的平均直径增加随着纺丝溶液的浓度的增加。在P4-VP/DMF纺丝溶液中加入TPPA后，由于P4-VP/DMF-TPPA溶液电导率的增加，P4-VP/TPPA纳米纤维的直径变得均匀。光致发光(PL)光谱分析表明，P4-VP/TPPA纳米纤维的发射峰位置与纯TPPA几乎相同，在650 nm左右，无峰移，并且在储存20天后，P4-VP/TPPA纳米纤维的发射峰也在650 nm处，说明P4-VP/TPPA纳米纤维的荧光性能稳定。傅里叶变换红外(FTIR)光谱证实了P4-VP/TPPA复合纳米纤维的化学成分。

Fabrication of Poly(4-vinylpyridine) Nanofiber and Fluorescent Poly(4-vinylpyridine)/Porphyrin Nanofiber by Electrospinning

Poly(4-vinylpyridine)(P4-VP) nanofiber and fluoresent poly(4-vinylpyridine)/porphyrin(P4-VP/TPPA) nanofiber were respectively prepared by electrospinning. The effect of the concentration of P4-VP/dimethylformamide (DMF) electrospinning solutions on the morphology of P4-VP nanofiber was investigated and it was found that the average diameter of the nanofiber of P4-VP/DMF increased with the increase of the concentration of the spinning solution. After the addition of TPPA to the P4-VP/DMF spinning solution, the diameter of P4-VP/TPPA nanofiber became even due to the increase of the conductivity of the P4-VP/DMF-TPPA solution. The photoluminescent(PL) spectral analysis indicates that the emission peak position of P4-VP/TPPA nanofiber is almost the same as that of pure TPPA at about 650 nm without peak shift, and when it was stored for 20 days, the emission peak of P4-VP/TPPA nanofiber is also at 650 nm, indicating that the fluorescent property of P4-VP/TPPA nanofiber is stable. Fourier-transform infrared(FTIR) spectrum confirms the chemical composition of the resulting P4-VP/TPPA composite nanofiber.
