Abstract
Barium titanate (BTO) has been extensively studied for its promise in increasing device performance with its high dielectric constant. With the world moving toward miniaturization, research in nanotechnology is paving a road for the future of electronics, energy storage, and batteries. A challenge in understanding BTO’s potential lies in the particles’ tendency to agglomerate. Nanoparticles behave differently than their bulk counterparts, so understanding size effects is a crucial step in understanding BTO. In this work, BTO nanoparticles are synthesized via a hydrolysis reaction, then functionalized via a ligand exchange reaction to reduce agglomeration. BTO is added to epoxy composites at different volume percents, allowing for capacitance measurements. Finally, these composites are sectioned to obtain transmission electron microscopy (TEM) data to be used to quantify agglomeration. In this work, tert-butyl phosphonic acid (tBuPA) reduced agglomeration, and as the volume loading of the composites increased, the dielectric constant increased.
