Dopamine functionalization of BaTiO3: An effective strategy for the enhancement of electrical, magnetoelectric and thermal properties of BaTiO3 - PVDF –TrFE nanocomposite

Abstract

Electro-active polymer-ceramic composite systems are emerging materials in the fields of nanoelectronics, microelectromechanical and macroelectronic device applications. Still more precise and concise researches have yet to come in the areas of energy storage, harvesting, energy conversion etc. In line with this we have synthesized and analyzed PVDF-TrFE based nanocomposites of both functionalized and non-functionalized BaTiO3 (BTO). All the samples were prepared as free standing films by employing solvent cast method. A systematic study in the structural, morphological, thermal, dielectric, ferroelectric, piezoelectric and magnetoelectric(ME) properties have been carried out. It has been analyzed that the addition of BTO nanoparticles (with and without functionalization) into the polymer matrix substantially improved the properties of the nanocomposite. By performing the above-mentioned characterizations it could be proved that dopamine functionalized BTO (DBTO) samples are better choices for the above mentioned applications including magnetoelectric applications, than non-functionalized ones.
