Comparison of various methods of grafting of modified-PEG onto maghemite nanoparticles in aqueous medium including synthesis by microwave refluxing
Source abstract
Abstract
Three methods in the synthesis of functionalized maghemite nanoparticles in aqueous medium by grafting triethoxysilane monomethylene-PEG (Si-mPEG) onto maghemite nanoparticles were compared including synthesis by microwave refluxing which is an original device designed by our research team. The maghemite nanoparticles were characterized by zeta potential measurement, X-ray diffraction (XRD), Raman spectroscopy, transmission electron microscopy (TEM) and Fourier transform infrared spectroscopy (FTIR). The spinel structure of maghemite nanoparticles was determined and successful grafting of m-PEG was evidenced. Thermogravimetric analysis (TGA) reveals that microwave heating tends to improve the grafting rate compared to conventional heating.
