Biocompatible Flexible Carbon Fabric for Joule Heaters With and Without Graphene Oxide Coating.

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.
