Abstract
A composite heat spreader includes a first flexible graphite layer, a second flexible graphite layer, and a gas evolving layer positioned between the first flexible graphite layer and the second flexible graphite layer. The gas evolving layer is temperature sensitive and when a threshold temperature is reached, the thermal conductivity of the gas evolving layer is reduced by at least factor of five.
