Thermal Transport Properties of Dry Spun Carbon Nanotube Sheets

الملخص EN

The thermal properties of carbon nanotube- (CNT-) sheet were explored and compared to copper in this study.

The CNT-sheet was made from dry spinning CNTs into a nonwoven sheet.

This nonwoven CNT-sheet has anisotropic properties in in-plane and out-of-plane directions.

The in-plane direction has much higher thermal conductivity than the out-of-plane direction.

The in-plane thermal conductivity was found by thermal flash analysis, and the out-of-plane thermal conductivity was found by a hot disk method.

The thermal irradiative properties were examined and compared to thermal transport theory.

The CNT-sheet was heated in the vacuum and the temperature was measured with an IR Camera.

The heat flux of CNT-sheet was compared to that of copper, and it was found that the CNT-sheet has significantly higher specific heat transfer properties compared to those of copper.

CNT-sheet is a potential candidate to replace copper in thermal transport applications where weight is a primary concern such as in the automobile, aircraft, and space industries.
