Sampleswere fabricated by casting a single layer of 25 mm thick polypropylene (TF-225-4, Premier Lab Supply, Inc., Port St Lucie, FL, USA) in a vacuum oven at 2008C into a 20 mm thick polycarbonate filter (Isopore, Millipore, Inc., Billerica, MA, USA) containing 0.6 mm diameter pores. The polycarbonate filter was etched in methylene chloride, and resulting samples were rinsed in isopropyl alcohol and air-dried.Flat control sampleswere produced by processing the 25 mm thick polypropylene film as above except without the use of the filter. |

Flat control samples were produced by processing the 25 mm thick polypropylene film as above except without the use of the filter. 通过在真空炉中及200℃下将25 mm厚的聚丙烯（TF-225-4, Premier Lab Supply公司， Port St Lucie, FL, USA）投入20 mm厚并含有0.6 mm直径孔的聚碳酸盐滤器(Isopore, Millipore公司， Billerica, MA, USA)中来制造样品。 在二氯甲烷中蚀刻聚碳酸盐滤器，且用异丙醇冲洗所得样品并将其风干。 通过根据上述方法处理25 mm厚的聚丙烯薄膜（但不使用滤器）来制造平坦对照样品。 |
