Summary

Introduction

Nanocomposites are very promising alternative that can be adapted to the requirements of materials with special chemical, electrical, and magnetic properties [1,2,3]. In-situ polymerization was focused on the electrochemical interaction between metal oxide ions and polymers followed by oxidation reduction reactions to obtain homogeneous material, and retain its; control of the nanoscale structure, size and shape of nanocomposites [13,14,15]. About 1.635g of m-aminophenol (map) was dissolved in 100 ml of 0.5M HCl. The oxidant Ammonium Persulphate (APS) 5.13 g was dissolved separately in minimum volume of water (25 ml) at room temperature. The same procedure was performed for the synthesis of Pmap/ Fe3O4 nanocomposite by insitu oxidative chemical polymerization using m-aminophenol and Ammonium persulphate. The APS solution was added drop wise to the reaction mixture with 45 minutes and stirred constantly for 4 hour at room temperature. Magnetic properties of the samples M Vs H @ Room Temperature were measured using a Lakeshore, USA, Model 7407 vibrating sample magnetometer
