Effect of graphene-based nano-electronic film on the insulation performance of thermal barrier coatings

In order to accurately analyse the effect of graphene on the thermal insulation performance of thermal barrier coatings, the effect of graphene nano-electronic films on the thermal insulation performance of thermal barrier coatings was studied. Graphene, graphene nano-electronic thin films and thermal barrier coatings were prepared by using the initial materials in the order of preparation. The experimental samples were divided into a control group and an experimental group, and the structure and content of the graphene nano-electronic thin films were changed to conduct an insulation performance experiment. The experimental results show that the thermal insulation coefficient is 0.32 when the film content is 3.0 μg/mg, and the maximum thermal insulation temperature of the thermal barrier coating is 800°C. When the graphene nano-electronic film has a double-layer structure and a content of 3.0 μg/mg, the thermal insulation effect is the best.
