Capacitive carbon nanotube networks in polymer composites

Carbon nanotube networks behave as capacitive elements in polymers and carrier transport across tube junctions resembles charging a capacitive tube/polymer/tube structure. Spin localization at interface is verified by electron paramagnetic resonance and a transport mechanism based on temperature con...

Description
Summary:Carbon nanotube networks behave as capacitive elements in polymers and carrier transport across tube junctions resembles charging a capacitive tube/polymer/tube structure. Spin localization at interface is verified by electron paramagnetic resonance and a transport mechanism based on temperature controlled free volume of polymer is proposed.
