ABSTRACT

The microwave absorption properties of polymer composite PANI/PVA/NiFe₂O₃ are investigated. The polymer composites of PANI/PVA and NiFe₂O₃ are prepared in two steps. NiFe₂O₃ is synthesized by modified sol gel method and PANI by chemical polymerization method. Microwave absorption parameters of polymer composite are measured at X-band. The microwave absorption is found to be -28 dB (99%) at 10.2 GHz. Different characterization techniques such as SEM-EDX, FTIR and XRD are done. The SEM result shows flakes like structure for PANI/PVA and crystalline structure for NiFe₂O₃. FTIR of the composite reveals the interaction between the PANI/PVA and NiFe₂O₃.
