摘　　要：使用静电纺丝的方法制备了一种含有硝基螺吡喃(SP)的具有光致变色特性的PMMA纤维。红外光谱(IR)的研究结果表明,SP可以通过络合反应与PMMA结合。通过扫描电镜(SEM)的观察可以看出,SP的加入对PMMA纤维的形态结构几乎没有影响。紫外可见光谱以及紫外光照后的颜色变化观察的结果表明,SP的加入使PMMA纤维具备了良好的光致变色性能。Poly（methyl methacrylate）（PMMA） fibers with photochromic capability were prepared by electro-spinning from a solution of PMMA and notro spiropyran（SP）.The complex reaction between the hydroxyl groups of SP and PMMA was verified by infrared spectrum（IR）.The results of scanning electron microscopy（SEM） indicated that the incorporation of SP exerted little influence on the morphology of PMMA fibers.The results of ultravioletvisible （UV-Vis） spectrophotometry and the evidences of color showed changes that SP could endow electrospun PMMA fibers with good photochromic properties.
