Abstract

Organic Nanodielectric Polymer Capacitors tainted with gold plating were prepared in this experiment using the hot press method to determine the effectiveness of their applications in energy storage by analyzing their energy density and D-E Loop. The results procured from this study demonstrated the feasibility of the organic copolymer, PTTHEMA-co-PBA capacitor and its possible applications for energy storage in comparison to the homopolymer, PTTHEMA. The copolymer was capable of reaching a field of about 120 MV/m, whereas; the homopolymer was only capable of reaching about 30 MV/m. The significant difference in their field strengths demonstrates the success of the copolymer transfer agent PBA. Moreover, charged and discharged electric energy densities of both the homopolymer and copolymer were examined by electric displacement-electric field (D-E) hysteresis loop measurements on pressed films. Similar to commercialized inorganic ceramic polymers such as biaxial-oriented polypropylene (BOPP), both polymers displayed strong linear correlation while demonstrating narrow D-E loops suggesting low dielectric loss. Furthermore, the copolymer capacitor shows better mechanical properties than the homopolymer and produced a freestanding film. Specifically, the apparent success of the copolymer over the homopolymer will be concluded, with the aim of developing novel, successful organic polymer capacitors that display low dielectric loss with high breakdown strengths. In essence, the outcome of this project determined the effectiveness of the organic copolymer capacitor as seen by comparing to the homopolymer base—with the hopes of finding an alternative and innovative method of encapsulating and accumulating energy at an economic, environmental, and production decrement.
