Hydrothermally prepared nano bricks of potassium sodium niobate for enhancing thermal and electrical properties of Poly(vinylidene fluoride)

摘要

? 2023 Elsevier B.V.This study presents the hydrothermal fabrication of K0.5Na0.5NbO3 nano bricks at a very lower temperature and its emphasis on the various properties of the polymer matrix. Even a smaller amount of such a nanostructured ceramic phase leaves a great influence on the various properties of the polymer matrix. Interestingly just a 10 loading of KNN (potassium sodium niobate) nano bricks in a polymer matrix alters the remanant polarization to 6.10 μC cm?2 from 0.04 μC cm?2 for PVDF Poly(vinylidene fluoride) and 7.3 μC cm?2 at 20 loading. The estimated dielectric at the frequency of 1 kHz shows more than 5 and 6 times increase at 10 (εr = 13) and 20 (εr = 15.4) of ceramic filler which is originally 2.5 for the pure PVDF matrix.
