- Abstract
- Resistance dependence on temperature and mechanical deformation (compression and tension) issues have to be solved, in order to utilize carbon nanotubes (CNT) polymer composite for practical heat-related applications. We report a resistance compensated laser printer fuser element using CNT composite that shows rapid heating properties. During electric heating (200 degrees C), highly conductive CNT/polydimethylsiloxane (PDMS) composites show a negative temperature coefficient (NTC) of resistivity resulting in the decrease of resistance (-14%), due to interconnection resistance between the CNTs. We redeem the NTC property through the use of the positive pressure coefficient effect of CNT/PDMS. In a paper-feeding test using a laser printer fuser system, CNT/PDMS film that was properly compressed by pressing roller (120 N/cm(2)) and heating roller showed a constant normalized resistance until 200 degrees C. The proposed laser printer fuser element could be used as a basis for heating unit applications.
