Abstract: A method of forming an polymer composites is disclosed herein that includes infiltrating CNT sponges with a polymer or metal to form a composite. The method uses a relatively easy, scalable, and low-cost synthesis process that makes the composites attractive as TIM. CNTs in the sponge structure are covalently bonded, resulting in a low Young's modulus while at the same time maintaining a good thermal conductivity. This strategy makes it possible to obtain both high deformability and high thermal conductivity, which are difficult to have simultaneously due to their adverse correlation.
