Nanowire Preparation in Ion-track Templates

The polymer foils irradiated by heavy ions can be used as templates to prepare metallic nanowires and some inorganic salt nanowires.It is called template method.Compared to other templates,such as AAO template and porous silicon,etched ion-track template is more convenient and flexible.The density of the pores can be easily controlled by changing the ion fluences and the diameter of the pores can be altered through changing the etching condition.The pores of the etched ion-track template are well aligned.We present some examples of preparing metallic nanowires and inorganic salt wires by electrochemical deposition and by supersaturation solution method,respectively.We also introduce some applications of nanowires prepared with ion-track template method.
