In this study, we demonstrate a carbon-based fabric Joule heater with and without a graphene oxide (GO) thin coating. The electrothermal performance of the carbon fabric used in the Joule heater was obtained using an infrared camera and by conducting electrical measurements. The outer GO could control the electrothermal efficiency and heating rate. In this research work, using the Joule heating of thin graphene films, we report adaptive thermal heating with electrical control covering temperatures ranging 30 to 50 °C (near infrared). This electrothermal GO materials can be potential nano-materials for various functional applications. Moreover, we demonstrate a general approach to achieve spin-coating of GO and confirm its biocompatibility Such biocompatibility indicates the non-toxic nature of GO, thereby extending its possible use in biomedical applications.
在这项研究中，我们展示了一种带有和不带有氧化石墨烯 (GO) 薄涂层的基于碳的织物焦耳加热器。使用红外摄像机和进行电气测量来获得焦耳加热器中使用的碳纤维织物的电热性能。外部 GO 可以控制电热效率和加热速率。在这项研究工作中，我们使用薄石墨烯薄膜的焦耳加热，报告了具有电控制的自适应热加热，其覆盖温度范围为 30 至 50°C（近红外）。这种电热 GO 材料可以成为各种功能应用的潜在纳米材料。此外，我们展示了一种实现 GO 旋涂的通用方法，并确认其具有生物相容性。这种生物相容性表明 GO 具有无毒性质，从而扩展了其在生物医学应用中的可能用途。
