Synthesis and Tailoring the Optimization and Dielectric Properties of PMMA/PEG/Barium Titanate Hybrid Nanostructures for Energy Storage and Electronics Applications

The present work aims to improve the dielectric properties of poly-methyl methacrylate (PMMA)- polyethylene glycol (PEG) blend doped with barium titanate (BaTiO3) nanoparticles to be useful in electronics and dielectric fields. The PMMA/PEG/BaTiO3 nanocomposite films were fabricated by using the casting method. The morphological and dielectric characteristics of PMMA/PEG/BaTiO3 nanocomposite films were tested. The dielectric characteristics were examined by LCR meter at frequencies ranging from 100 Hz to 5 MHz. The results of dielectric characteristics confirmed that there is a growth in the dielectric parameters of PMMA/PEG blend with increasing BaTiO3 NPs content. The dielectric properties of PMMA/PEG/BaTiO3 nanocomposite films were distorted with a boost of the frequency. Finally, dielectric characteristics show that the PMMA/PEG/BaTiO3 nanocomposite films can be utilized in various electrical and nanoelectronics applications with high energy storage, lightweight, low cost, and flexibility.
