High emissivity coatings have received a great attention due to their energy saving capability for using in spacecraft and industrial furnaces applications. In this study, a feasible spray deposition method was employed to prepare a high emissivity coating on Kovar alloy substrate with porous structure after heat treatment. Graphene oxide was used to dope coating to improve its emissivity. The emissivity enhancement mechanisms of the graphene oxide doped SiO₂ coatings have been investigated. Results show that coating emissivity can be significantly improved (6.41 and 9.64% of coating emissivity at 500 and 800°C, respectively) by doping graphene oxide. Thus, this study proposed a feasible and effective method to prepare high emissivity coatings. © 2019 Wiley Periodicals, Inc. J. Appl. Polym. Sci. 2020, 137, 48794.

掺杂氧化石墨烯对SiO2基高发射率涂层结构和性能的影响

高发射率涂层由于其在航天器和工业炉应用中的节能能力而备受关注。在这项研究中，采用可行的喷涂方法在热处理后在具有多孔结构的科瓦合金基材上制备高发射率涂层。氧化石墨烯用于掺杂涂料以提高其发射率。研究了掺杂氧化石墨烯的SiO ₂涂层的发射率增强机理。结果表明，通过掺杂氧化石墨烯可以显着提高涂层的发射率（分别在500和800°C时分别达到涂层发射率的6.41％和9.64％）。因此，本研究提出了一种可行且有效的制备高发射率涂层的方法。分级为4 +©2019 Wiley Periodicals，Inc.J.Appl。Polym。科学2020，137，48794。
