Polymer nanocomposite films doped with piezoelectric metal oxide nanoparticles have attracted significant attention due to their potential applications in flexible electronics, sensors, and energy harvesting devices. This research investigates the structure-property correlations in polymer nanocomposite films composed of ethylene vinyl acetate (EVA) doped with piezoelectric metal oxide nanoparticles, specifically Potassium Sodium Niobate (KNN) and Lithium Niobate (LiNbO3). EVA, a copolymer of semi-crystalline polyethylene and amorphous vinyl acetate, provides tunable material properties, making it an ideal matrix for functional nanocomposites. Morphological analysis using SEM and AFM confirmed homogeneous nanoparticle dispersion across different EVA compositions. Structural characterization through XRD and FTIR revealed increased crystallinity and polymer-nanoparticle interactions in doped films. Mechanical testing showed tensile strength from 2 to 13 MPa for 15 % KNN, and 30 % LiNbO3, indicating mechanical reinforcement while maintaining flexibility. These findings demonstrate the potential of KNN- and LiNbO-doped EVA films for flexible electronics, sensors, energy harvesters, and biomedical applications, providing a tunable platform where mechanical reinforcement and piezoelectric responsiveness are simultaneously achieved. |
