| Abstract: | The ternary coniplexe of europium with citric acid and 1,10-phenanthroline(Eu(Cit)Phen)with hydroxyl group and prepolymer of polyurethane(PU)with isocyanate groups-terminated were synthesized. Under the chain extension action of 1,3-propylene glycol,covalently bonded PU/complexes rare earth materials were prepared by the ternary complexes and PU prepolymer via additive reaction of hydroxyl and isocyanate groups.Fluorescent nanofibers derived from the PU/complexes materials were prepared via electrospinning ... |
