摘　　要：通过高压静电纺丝方法实现了微米/纳米材料的自组装和图案化,建立了一个在高压电场诱导下的微米/纳米材料的连续化形成的新方法,电镜结果表明聚乙烯吡咯烷酮(简称PVP)/锰卟啉纤维直径在3～4μm,长度在几百微米,实验中,卟啉环在锰卟啉/PVP系统中形成π-π堆积,形成面-面排列的堆积效应,这种驱动力是促进超分子化合物自组装的一种很好的构筑方式。Functional self-assembled structure with well-defined shapes and dimensions are of great current interest.Porphyrins are attractive building manifold patterning for these structures because of their electronic,optical,and catalytic properties.In this paper,we report a novel technique for the assembly patterning of polymers.An electrospinning process was used to create patterning with diameter ranging from 3 to 4 μm and length of up to several hundred micrometers in the presence of Mn Porphyrin.Scanning electron microscopy （SEM） were used to characterize the patterning.As a possibly mechanism,the formation of the micro-patterning might be attribute to the hydrogen bonding and the π-π stack in porphyrin ring（loop）.
