1. A heat dissipation system comprising:
a substrate;
a plurality of heat dissipating layers on at least a portion of the substrate, each one of the plurality of heat dissipating layers comprising:
(i) a gradient nanoparticle layer comprising a plurality of nanoparticles including first nanoparticles each having a first diameter and second nanoparticles each having a second diameter, wherein the first diameter and the second diameter differ from one another in length by 10% or more and wherein each of the first diameter and the second diameter is less than 500 nm in length; and
(ii) a carbon allotrope layer disposed adjacent to the gradient nanoparticle layer, the carbon allotrope layer comprising a plurality of carbon allotrope particles suspended in a matrix, wherein the matrix comprises one or more polymers heat stable up to 500 C.
 
12. A method of dissipating heat, the method comprising:
applying a plurality of heat dissipating layers on at least a portion of a substrate, wherein the plurality of heat dissipating layers each comprise:
(i) a gradient nanoparticle layer comprising a plurality of nanoparticles including first nanoparticles each having a first diameter and second nanoparticles each having a second diameter, wherein the first diameter and the second diameter differ from one another in length by 10% or more and wherein each of the first diameter and the second diameter is less than 500 nm in length; and
(ii) a carbon allotrope layer disposed adjacent to the gradient nanoparticle layer, the carbon allotrope layer comprising a plurality of carbon allotrope particles suspended in a matrix, wherein the matrix comprises one or more polymers heat stable up to 500 C; and
exposing the plurality of heat dissipating layers to a heat source.
