Synthesis and Characterization of Ni0.5Co0.5Tio3 Composite with Polyvinyl Alcohol (PVA) as Microwave Absorber

Ni0,5Co0,5TiO3 composites are included in the category of magnetic materials with a perovskite structure that has great potential as a microwave absorbers due to their superior magnetic and dielectric properties, which are important for reducing electromagnetic interference (EMI). To improve the electromagnetic properties, Ni0,5Co0,5TiO3 composites are mixed with conductive polymers such as Polyvinyl Alcohol (PVA). This research synthesizes Ni0,5Co0,5TiO3 via solid-state mechanical milling techniques and characterizes its crystal structure, morphology, and microwave absorption capacity. The addition of PVA in this composite aims to increase the flexibility of the material while maintaining its absorption capacity. Based on the research conducted, the physical and electromagnetic properties of the composite are greatly influenced by the synthesis method, particle morphology, and cation distribution in crystal structure. This research focuses on the effect of the combination of Ni0,5Co0,5TiO3 with PVA on microwave absorption efficiency, which is measured by the reflection loss value.
