摘要
Poly(4-vinylpyridine)(P4-VP)nanofiberandfluoresentpoly(4-vinylpyridine)/porphyrin(P4-VP/TPPA)nanofiberwererespectivelypreparedbyelectrospinning.TheeffectoftheconcentrationofP4-VP/dimethylformamide(DMF)electrospinningsolutionsonthemorphologyofP4-VPnanofiberwasinvestigatedanditwasfoundthattheaveragediameterofthenanofiberofP4-VP/DMFincreasedwiththeincreaseoftheconcentrationofthespinningsolution.AftertheadditionofTPPAtotheP4-VP/DMFspinningsolution,thediameterofP4-VP/TPPAnanofiberbecameevenduetotheincreaseoftheconductivityoftheP4-VP/DMF-TPPAsolution.Thephotoluminescent(PL)spectralanalysisindicatesthattheemissionpeakpositionofP4-VP/TPPAnanofiberisalmostthesameasthatofpureTPPAatabout650nmwithoutpeakshift,andwhenitwasstoredfor20days,theemissionpeakofP4-VP/TPPAnanofiberisalsoat650nm,indicatingthatthefluorescentpropertyofP4-VP/TPPAnanofiberisstable.Fourier-transforminfrared(FTIR)spectrumconfirmsthechemicalcompositionoftheresultingP4-VP/TPPAcompositenanofiber.
