Abstract

In this paper, we observed stretching of carbon nanotube (CNT) aggregates driven by the electric filed in a nematic liquid crystal (LC) medium. The CNT aggregates started to stretch above a threshold filed which is $1.5\;V/{\mu}m$ and the original CNT length which is $1.7{\mu}m$ was stretching up to $19.2\;{\mu}m$ at $3.5\;V/{\mu}m$ electric filed. When the CNT aggregates became to stretching, the width and length of CNT aggregates became narrow and long, respectively. The original morphology of the CNT aggregates was restored upon removal of filed.
