Effect of Magnetic Nanohybrid on the Structure-Property Relationship of Poly(Styrene) Based Copolymer

A novel random copolymer nanocomposite was synthesized by a three step process. In the first step a magnetic nanohybrid was prepared and a random copolymer was synthesized by an emulsion method in the second step. In the third step, a random copolymer nanocomposite was prepared. An FTIR and H-1-NMR spectra were used to confirm the chemical structure of the materials. The DSC and TGA results declared that the T-g and T-d of the nanocomposite was increased by increasing the % weight loading of the magnetic nanohybrid. The M-w of the nanocomposite was increased due to the chemical grafting of magnetic nanohybrid onto the random copolymer backbone. Due to the encapsulation effect the magnetic moment value of the nanocomposite decreased. The catalytic activity of the nanocomposite was tested towards the reduction of p-nitrophenol (NiP). The present methodology offers a heterogeneous, magnetic and fluorescent catalyst.
