| Popis: | This paper presents the characterization of solar heat absorber coatings on metal sheets using reduced graphene oxide polymer composites. The reduced graphene oxide (rGO) polymer composite material was evenly coated by the silk-screen method on three types of metal sheets. The thickness of the coated sheet samples was 0.25 mm which were exposed under solar radiation and the variations in temperatures versus time were recorded. The influence of solar radiation and angle of incidence during peak hours was recorded. The results show that stainless steel coated by rGO absorber gain more heat than other metal sheet absorbers. These coatings have a promising scope in solar thermal applications and the technique is cost-effective to characterize efficient solar absorber coatings. |
