Particles having a relatively high porosity can be used in an information handling system or other information handling system. In one aspect, a portable information handling system can include an electrical circuit that can generate thermal energy during normal operation of the electrical circuit.

Particles having a relatively high porosity can be used in an information handling system or other information handling system. In one aspect, a portable information handling system can include an electrical circuit that can generate thermal energy during normal operation of the electrical circuit. The portable information handling system can also include a housing that includes a first material and particles having a porosity of at least 80%. In another aspect, an information handling system can include a housing that includes a material and a coating, wherein the coating includes a polymeric material and particles having a porosity of at least 80%. In another aspect, a process of forming an information handling system can include coating a surface of a housing, wherein the coating includes particles having a porosity of at least 80%, and placing an electrical circuit within the housing after coating the surface.
