摘　　要：为制备具有荧光功能的纤维素纳微米发光纤维,将有机稀土发光材料引入到纤维素纺丝溶液中,通过对静电纺丝过程中的各工艺参数的优化,实现对纤维素基本形貌进行在线调控,成功制备了纤维丝束和直径分布较均匀的具有防伪标识功能的新型绿色环保纤维素纳微米发光纤维。场发射扫描电镜和荧光分光光度计的测试结果表明:当纺丝溶液质量分数为3.6%、纺丝电压为16 kV、推进速率为1.4 mL/h时所制备的样品结构和性能最佳;纤维样品的荧光强度随添加的稀土发光材料的增加而增强,当Tb(BAO)3(Phen)的质量分数为10%时,所制备的样品在紫外光激发下会呈现出较好的荧光,其使用寿命也非常持久,纤维膜的荧光强度在480 d后无明显变化。因此,将纤维素的可降解性和稀土发光材料的优异荧光防伪特性有机结合可制备具有防伪标识功能的纤维素纳微米发光纤维。In order to prepare nano-micron luminescent cellulose fibers with fluorescence function, organic rare earth luminescent material was introduced into the cellulose spinning solution, and the morphology of cellulose fibers was controlled by optimizing the process parameters in the electrospinning process. The novel green environmentally friendly cellulose nano-micron luminescent fibers with anti-counterfeiting function were prepared. As-prepared cellulose nano-micron luminescent fibers have uniform distribution on the diameter of fibers. Results coming from field emission scanning electron microscopy and fluorescence spectrophotometer show that the as-prepared sample has the best structure and performance when the concentration of the spinning solution is 3.6%, the spinning voltage is 16 kV, the advancing speed is 1.4 mL/h. The fluorescence intensity of fiber samples was enhanced with the addition of rare earth luminescent materials. When the mass percentage of Tb(BAO)3(Phen) is 10%, the prepared samples can exhibit better fluorescence under ultraviolet light excitation. And its service life is also very long-lasting. The fluorescence intensity of fiber membrane has no obvious change after 480 d. Therefore, combining the degradability of cellulose and the excellent fluorescent anti-counterfeiting properties of rare earth luminescent materials can prepare cellulose nano-micron luminescent fibers with anti-counterfeit marking function.
