Abstract
Heat dissipation systems include a plurality of heat dissipating layers, including gradient nanoparticle layers and carbon allotrope layers, applied to substrates. The gradient nanoparticle layers have first and second nanoparticles that both have diameters less than 500 nm, and the diameters differ from one another in length by 10% or more. The carbon allotrope layers include carbon allotrope particles suspended in a matrix that includes one or more polymers heat stable up to 500 C.
