Improvement of dielectric and structural characteristics of Nanofiller (Ba0.92Sr0.08 )TiO3 Ceramics combined with epoxy as composites for dielectric purposes

Polymer Nano composites were created by reinforcing epoxy with barium titanate (B 0.92 S 0.08 ) TiO 3 , boasting high dielectric strength. These composites showcased significant alterations in their dielectric capabilities, influenced by time, temperature, and concentration. The research delved into epoxy resin composites, exploring how the ratio of BST nanoparticles affected the dielectric strength concerning the epoxy aspect ratio. Epoxy was combined with nano filler titanate (B 0.92 S 0.08 ) TiO 3 Ceramics at various BST to epoxy ratios of 0%, 2.5%, 5%, 7%, and 100%, with the mixture left to cure in an oven at temperatures of 40°C, 50°C, 60°C, and 80°C for durations ranging from 10 to 50 minutes. The temperature was consistently set at 50°C, while curing times varied from 10 to 50 minutes. The study also delved into the mechanical bonding mechanisms between BST and epoxy polymer. Techniques such as Scanning Electron Microscopy (SEM) and Transmission Electron Microscopy (TEM) were employed to study delaminated layers, inspect fracture surfaces, and assess structural features and dielectric strength. Discussions revolved around the impacts of concentration, particle size, and BST filler on the dielectric properties of BST/polymer composites. Artificial Neural Networks, known as ANNs, mimic the intricate workings of the human brain to delve into the realms of ceramic/polymer composites' dielectric constants and the crafting of BST/polymer composites. Delving deeper, the enhancement of dielectric constants in BST/polymer composites is succinctly outlined. A novel theoretical model focusing on dielectric constants, drawn from our prior research endeavors, is presented. Furthermore, the impacts of various factors on the dielectric constants of these composites are explored, aiding in the forecast of their dielectric constants. This discussion holds significant theoretical and research implications for future endeavors.
