Synthesize uniform carbon nanocoils by anodic aluminum oxide

In this study, we utilized porous anodic aluminum oxide (AAO) template to assist synthesizing carbon nanocoils with high uniformity. By confining the space of growth, we have successfully obtained carbon nanocoils with superior uniformity. Synthesizing carbon nanocoils with catalytic thermal chemical vapor deposition assisted by removable anodic aluminum oxide template. We obtained uniform carbon nanocoils which has coil diameter between 100 ~ 500 nm, pitch between 100 ~ 500 nm, and fiber diameter between 60 ~ 260 nm, both were decreased more than 50 percent compared with which growth without the template. The approach of synthesizing CNCs with superior uniformity is able to be extensively integrated into electronic devices for further applications
