ABSTRACT
MIL-101-Fe (Materials of Institute Lavoisier) metal organic framework (MOF) was synthesized by solvothermal method. Further, surface of the as prepared MIL-101-Fe is with Polyethylene glycol (PEG). FESEM and TEM micrograph of MIL-101- Fe and PEGylated MIL-101-Fe particles showed hexagonal shaped morphology with particle size in the range of 400–500 nm and 600-700 nm respectively. The DLS spectra also show the similar results. This increase in size of the particles indicates the presence of PEG layer on the surface of the MOFs. FTIR characterization was further conducted to detect the functional groups of the MIL-101(Fe) and after PEG coating. These results confirm the presence of PEG in MIL-101(Fe) framework.
