Study on existence of CNT in nanocomposite CNT/MEH-PPV thin film

Abstract

Spin coating method is used to deposit nanocomposite CNT/MEH-PPV thin film on a glass substrate. The MEH-PPV which is in powder form was weighted and then dissolved into THF. Then, a certain amount of CNTs were added to the MEH-PPV solution. It is then stirred for 3 hours and sonicated for 1 hour to ensure that CNTs is well dispersed in the MEH-PPV solution. The addition of CNTs in the MEH-PPV solution yields a nanocomposite CNT/MEH-PPV solution. The characterization done was to evaluate the conductance as well as the absorption. The conductance and absorption of the nanocomposite showed an increment in value due to the existence of the CNTs.
