Özet
In this study, it is aimed to develop dielectric materials with highdielectric coefficient for flexible capacitors. For this purpose, MgO/CuO nanoparticles were first synthesized by precipitation reactions. Then, theseparticles were added together with graphene nanoplates (GNPs) into PVDF indifferent compositions to form a composite mixture. After this process, flexiblecomposite films of 30 ?m thickness were formed with doctor blade and phaseinversion methods. In the characterization processes, it was determined thatMgO/CuO particles were successfully produced with an average size of 282 nm. Onthe other hand, the highest capacitance and dielectric coefficient values of thecomposite films were determined in the GNPs@MgO/CuO@PVDF sample as 2.8 nFand 42.6 at 100 Hz frequency, respectively. As a result, it was concluded that thedielectric properties were significantly improved with the use of graphene andmetal oxides together, and PVDF was very successful in terms of flexibility andbinding role.
