Abstract
Phase change material-carbon nanotube-metal substrate composites and methods of making and using thereof are described herein. Such composites allow for thermal storage and passive or combined active/passive thermal control of heat generating sources, such as in electronic devices.
Claims46
A composite material comprising:
- a phase change material;
- vertically aligned carbon nanotube array supported on a substrate;
- and
- wherein all or substantially all void space present within the vertically aligned carbon nanotubes (CNTs) is filled by the phase change material.
A method of making a composite material, the method comprising:
- providing one or more vertically aligned carbon nanotube arrays supported on a substrate;
- and
- infiltrating a phase change material to the vertically aligned carbon nanotube arrays supported on a substrate wherein all or substantially all void space present within the vertically aligned carbon nanotubes (CNTs) is filled by the phase change material.
The method of claim 38, wherein the polymeric material is an adhesive.
The method of claim 43, wherein the stacked arrays form interfacing tiers between the two or more of the vertically aligned CNTs which are interdigitated within one another.
The method of claim 44, wherein the number of interfacing tiers in the stack is 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, or 25.
