Preparation of polymer template with porous array structure

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 obtained 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.
