Epoxy-based A recently conducted study presents a novel, lightweight, thermallyconductive, easily processed, mechanically robust, epoxy-based nanocomposite coating. The material was developed with the intention of bringing a multi-domain airwater drone to the deep ocean. In the work, the coating is thoroughly characterised and demonstrated to protect electronics submerged in water at high-pressure benchtop conditions as well as in an actual deep sea mission. The coating was also contrasted against unmodified epoxy as well as commercial syntactic foam and deemed superior for this application.
