Self-standing polystyrene nanotube (PNT) membranes have been fabricated from liquid deposition in the pores of anodic alumina. PNTs were deposited using 3 wt% concentration of 90 kDa polystyrene in the starting solution, followed by 2 h annealing in Argon. Initial polymer concentration, polymer molecular weight and annealing time were varied, and their impact on water flow through the nanotubes assessed. These results open the way to creating PNT membranes with well-defined pores of low tortuosity and tuneable surface properties, overcoming the limits of current polymeric membranes, whose internal transport pathway cannot be controlled or defined as well as for the case of the PNTs presented here.

自立式聚苯乙烯纳米管（PNT）膜是通过液相沉积在阳极氧化铝的孔中制成的。在起始溶液中使用3 wt％浓度的90 kDa聚苯乙烯沉积PNT，然后在氩气中退火2 h。改变初始聚合物浓度，聚合物分子量和退火时间，并评估它们对流经纳米管的水的影响。这些结果为创建具有低曲折度和可调节表面特性的明确定义的孔的PNT膜开辟了道路，克服了目前无法控制或定义其内部传输途径的聚合物膜的局限性，对于此处介绍的PNT而言。
