Moreover, AC is easy to be synthesized that lead to a reasonable price range compared to other carbon materials.
AC is often used as an electrode material in energy storage devices [6], but its advantages in structure properties could make them one of the influential materials for composites.
Rubber materials may suit various industrial applications, such as tire component, electrical shield, shock damper, and vibration-proof [7].
