Mechanical and Dielectric Properties of Polyhedral Oligomeric Silsesquioxanes Modified Graphene Oxide/Polyimide Nanocomposites

, , , , , , ,
An effective method is proposed to prepare octa(aminophenyl) silsesquioxane (OAPS) functionalized graphene oxide (GO) reinforced polyimide (PI) composites with a low dielectric constant and ultra-high mechanical properties. The amine-functionalized surface of OAPS-GO is a versatile [...]
