Synthesis and characterisation of poly(epichlorohydrin-g-Fe3O4/congo red)-co-poly(methylmethacrylate)

Abstract

weight average molecular weight (M w ) of the copolymer and nanohybrid-grafted copolymer exhibited higher M w than that of the PECH homopolymer. In the present study, we simply prepared a novel material and characterized it by various analytical methods.Abstract A magnetic and fluorescent copolymer nanocomposite was prepared and characterized by various analytical techniques. Poly(epichlorohydrin) (PECH) was prepared by solution polymerization method using methacrylic acid as a chemical initiator and its copolymer was prepared by emulsion polymerization. After the structural modification of the copolymer with a nanohybrid system, its thermal properties were improved. The nanohybrid system consisting of Congo red dye decorated ferrite nanoparticles was synthesized by the conventional method and characterized by UV-Visible, fluorescence emission and excitation spectroscopy methods, high resolution transmission electron microscopy, and vibrating sample magnetometer techniques. Due to the decoration and encapsulation phenomena, the magnetic moment value of Fe 3 O 4 was found to be decreased. While increasing the loading of nanohybrid system, the glass transition temperature (T g ) of poly(methylmethacrylate) was increased. The TGA study inferred that by increasing the loading of nanohybrid system, the percentage weight residue remained above 550 °C was also increased. The chemical grafting of nanohybrid system onto the PECH-based copolymer backbone was confirmed by NMR spectroscopy and GPC analysis.

Synthesis and characterization of magnetic and fluorescent styrene co‐polymer nanofiber

“…The M w , M n , and PD values were determined as 1.39 × 10 5 g/mol, 7.59 × 10 4 and 1.84, respectively. The increase in M n and M w values confirms the chemical grafting of the nanohybrid on the random co‐polymer backbone without any crosslinking . Molecular weight is one of the important factors to form a fiber.…”
