摘　　要：金属纳米线阵列是X射线强辐射源研究中的重要材料之一,针对物理实验对纳米线阵列结构尺寸的特殊要求,采用集束热拉伸法制备了包埋高度取向的聚苯乙烯微纳米线有序阵列的聚乙烯复合丝,经切片、选择性溶解等后处理得到多孔聚乙烯模板材料。光学显微镜及扫描电镜(SEM)观测表明,模板中的小孔呈较规则的阵列结构分布,其孔径可在200nm到几十μm之间调节,孔间距可在1μm到几十μm之间调节。通过比较实验的预设值和实测值表明,该方法可以实现对模板结构尺寸的设计和控制,进而将实现对纳米线阵列的尺寸控制。Metal nanowires array is one of the important materials for the research of X-ray intense radiation source. To meet the demand of physical experiment, well-ordered, globally oriented polyethylene composite fiber embedding micro or nanowires array of polystyrene was prepared by bundling and melt drawing technology, porous polyethylene template was ob rained after section cutting and dissolving processes. Optical microscope and SEM results show regular porous array structure in the template. And the pore size can be adjusted in the range from two hundred nanometers to tens of microns, the spacing of pores can be adjusted in the range from one to tens of microns. According to the designed size and the measured value, the size of the template can be designed and controlled by this method, which indicates that the size control of the nanowires array could be realized.
