Polyaniline nanocomposites with doped ferrites as an electromagnetic shield

Polyaniline (PANI) possesses good microwave absorption properties, with the maximum absorption rate of 15.8 dB, and greater than 10 dB within the frequency of 11.36-15.46 GHz. On mixing PANI in-situ with hybrid ferrites and doped ferrites, the resulting polyaniline nanocomposites (PANI NCs) behave as promising electromagnetic shield for a wide range of electromagnetic spectrum from 3GHz to 15.9GHz efficiently. In this review, literature on magnetic properties of Ni ferrite PANI NCs, NiGd ferrite PANI NCs, MnZn ferrite PANI and Sm3+ doped ferrite PANI NCs has been analyzed. In brief, the objective of this article is to emphasize on the preparation, processability and the application of the nanohybrids of polyaniline as a shield for the absorption of electromagnetic radiations.
