采用简单的离子辐照方法，在室温下在Nafion衬底上实现了高度透明和柔性的纳米结构(纳米锥、纳米针、纳米球)的形状控制制备。通过改变离子入射角和辐照离子，表面形貌和取向逐渐由纳米锥形转变为纳米墙图案。有趣的是，离子辐照到Nafion表面，在离子辐照之前，通过在衬底上添加任何材料，可以在没有表面修饰的情况下得到系统的图案。与裸衬底相比，纳米结构的减反射性能使其表面更加透明。并对不同形状纳米结构阵列的生长机理进行了简要的讨论。这种简单快速的方法被认为对在不同类型的塑料衬底上进行表面工程和制造尺寸可控的减反射纳米结构非常有吸引力。这些类型的透明纳米结构可能在各种领域具有显著的商业影响，如无尘设备、透明设备、纳米流体和药物输送。
Shape controlled fabrication of highly transparent and flexible nanostructures (nanocone, nanoneedle, nanowalls) onto nafion substrate were performed at room temperature by simple ion irradiation method. By varying the ion incidence angle and irradiated ion, the surface morphology and alignment were gradually changed from nanocone to nanowall pattern. Interestingly, ion irradiation onto the nafion surface led to the systematic pattern without surface modification by external addition of any material onto the substrate prior to ion irradiation. The antireflective performance of the nanostructures made the surface more transparent compared to the bare substrate. The growth mechanism of the nanostructures arrays with different shapes is also discussed briefly. This straightforward and fast method is thought to be very enticing for surface engineering and fabrication of antireflective nanostructures of controlled dimension onto different kinds of plastic substrates. These kinds of transparent nanostructures might have a remarkable role for promising commercial impact in wide variety of areas such as dust-free devices, see-through devices, nanofluidics, and drug delivery.
