Fabrication of through-hole membrane with anodic alumina nanohole array
We demonstrated two new methods to obtain through-hole membranes with an anodic alumina nanohole array. The two methods involved nanoimprinting, anodization, sputtering and dissolution in NaOH. A nanohole array with a pitch of 440nm was obtained. Through-hole membranes with a thickness of about 10?m were obtained. Through-hole membranes with 50 and 150nm-thick walls were obtained by the two methods.
