Abstract
A piston for an internal combustion engine with a piston crown having an outer surface and with a thermal management layer. The thermal management layer contains a functional layer. The functional layer in turn contains a functional layer matrix, wherein the functional layer matrix includes polysiloxane and hollow spheres embedded in the functional layer matrix. The thermal conductivity of the functional layer is in the range of 0.2 to 2 W/(m*K) and the heat penetration coefficient of the functional layer is in the range of 400 to 1200 J/(K*m2*s½).
