Thermal Spreading in Carbon Nanotube Coating

Area of Science:

• Materials Science
• Nanotechnology
• Thermal Engineering

Background:

• Carbon nanomaterials like carbon nanotubes (CNTs) and graphene are promising for heat spreading due to high thermal conductivity.
• Industrial reports on carbon-based nanofilms show remarkable thermal performance, but mechanisms and validity require further investigation.

Purpose of the Study:

• To methodically assess the thermal spreading performance of multi-walled CNT films on copper foil.
• To discuss the potential of carbon nanofilms as effective heat spreaders through experimental and numerical analysis.

Main Methods:

• Utilized a non-contact characterization method to evaluate thermal spreading.
• Conducted experimental assessments and numerical simulations for multi-walled CNT films on copper foil.

Main Results:

• Experimental and numerical data were gathered on the thermal spreading capabilities of CNT films.
• The study provides insights into the heat transfer enhancement mechanisms of carbon nanofilms.

Conclusions:

• Carbon nanofilms demonstrate potential as effective heat spreaders.
• Findings contribute to the development of high-performance carbon-based heat-spreading coatings.
