Abstract

Surface functionalization of BaTiO₃ nanoparticles with dopamine was carried out using a reflux method to strongly bind dopamine on the BaTiO₃ nanoparticle surface and improve its compatibility with the polyvinylidene fluoride (PVDF) polymer matrix. Fourier transform infrared spectra confirm the successful surface functionalization of BaTiO₃ nanoparticles after immobilization with dopamine. Electrical properties of the resultant nanocomposite show that the dielectric constant can be enhanced up to 56.8 with low dielectric loss.
