摘要

This study focuses on developing and characterizing carbon/iron oxide/polymer matrix hybrid nanocomposites designed to function as compact material systems for energy storage and harvesting. A series of polymer nanocomposites was developed using nanodiamonds and magnetite nanoparticles as reinforcing phase, varying the filler type and content. The energy storage capabilities of the systems were assessed under both AC and DC conditions to determine the effects of temperature, charging DC voltage level, and different filler contents on the stored and harvested energy. Experimental results confirmed that these systems could store and release energy on demand through a fast charge/discharge process. The inclusion of ceramic nanoparticles significantly enhances the energy density as well as the thermal and structural integrity of the systems. Finally, the energy efficiency of the systems was evaluated reaching its peak at a recorded coefficient value of 87.1%.
