Abstract
Dielectric materials are important electric materials that can find use in various applications, such as energy storage, wireless antenna communication, and microelectronics. However, traditional dielectric polymers often suffer from poor dielectric loss and thermal stability, while conventional dielectric ceramics face limitations due to their relatively high dielectric constant, heavy weight, and low load capacities. The emergence of bi-continuous dielectric composites, particularly those combining dielectric ceramics and polymers, offers a promising solution. This paper investigates the influence of interface shape and size on the dielectric properties of bi-continuous dielectric composites. An additive manufacturing (AM) approach was employed for sample fabrication, followed by a comprehensive debinding and sintering process. The impact of interface geometry on piezoelectric and dielectric properties was studied through various shapes. The results indicate that the number of turns, width, and surface area of an interface have a negative correlation with the capacitance, with a flat interface exhibiting the highest capacitance. The research contributes insights into designing and manufacturing highly tailorable dielectric materials, offering a pathway for refining smart material design and energy-efficient applications.
