Thermally Conductive Composition Comprising Thermally Conductive Carbon Nanotubes and a Continuous Metal Phase

Simple SummaryContent extracted from patent full text and abstract with AI.

This invention discloses a thermally conductive composition that includes carbon nanotubes (CNTs), which have been surface-modified with polymers and metal ions or metal oxides, dispersed uniformly within a continuous metal phase (such as aluminum, copper, or other listed metals). The method describes how to produce polymer-modified CNTs and how to incorporate them homogeneously into a metal matrix, resulting in a material with excellent thermal conductivity, low density, and adjustable thermal expansion. This material is particularly designed for improved heat dissipation in electronic devices and semiconductor components.
