Micropatterning of Vertically aligned Carbon Nanotubes Array (2013-2019)

Multiwalled CNT array, also known as VACNTs/CNT forest, exhibits remarkable optical reflection when bent and flattened in bulk. This exceptional reflection from the patterned CNT surface could help to develop flexible micromirrors array. Our research investigated the mechanical bending process of the CNT forest and various optical properties of the flattened CNT surface. We found that a controlled rolling process could create an aligned and highly smooth CNT surface and exhibits anisotropic optical reflection that can be exploited to develop an angular sensor.
