It has been argued that nanoparticle layers cause changes in heat transfer coefficient and CHF. In this study, in order to investigate the relationship between the properties of the nanoparticle layer and CHF, the surface of the nanoparticle layer was observed before and after CHF, and changes in the properties of the nanoparticle layer due to CHF were investigated. After CHF, the nanoparticle layer peeled and the surface the properties of nanoparticle layer changed.
