摘　　要：采用静电纺丝技术,以实验室自制的键合型铽聚合物为原料构建荧光纤维,通过调控聚合物溶液性质溶剂体系和电导率两个参数,来调控纤维的微观形貌,并考察其发光性能。当V(DCE)∶V(DMF)=1∶2时,纤维的表面光滑、直径最小,发光性能最佳;当加入导电盐四丁基氯化胺时,提高了溶液电导率,纤维直径进一步减小,但发光性能反而下降,是因为四丁基氯化胺显弱酸性,导致发光性能略有下降。采用V(DCE)∶V(DMF)=1∶2溶剂体系的纤维,与纸浆混合制得荧光防伪纸张,获得了隐蔽性和防伪性兼具的荧光防伪纤维,可拓展应用于钞票、票据、有价证券等重要领域。Fluorescent fibers were constructed from self-made bonded terbium polymer by electrospinning.The microstructure of the fibers was tuned and the luminescent properties were investigated by adjusting the properties of polymer solution such as solvent system and conductivity.The surface of the fibers is smooth,the diameter is the smallest,and the luminescent property is the best when V(DCE)∶V(DMF)=1∶2.When tetrabutyl ammonium chloride is added,the conductivity of the solution increases,the fiber diameter further reduces,but the luminescent performance deteriorates instead,because tetrabutyl ammonium chloride is weakly acidic.Fluorescence anti-counterfeiting paper was prepared by mixing pulp and fibers with V(DCE)∶V(DMF)=1∶2 solvent system.Fluorescent anti-counterfeiting fibers with both concealment and anti-counterfeiting properties were obtained.They can be applied to banknotes,bills,securities,and other important fields.
