Abstract
A metal-organic framework (MOFs) material UiO-66-Br was synthesized via hydrothermal method, and the surface initiated metal-free atom transfer radical polymerization (SI-metal-free ATRP) of methyl methacrylate (MMA) and Eu complex were initiated on UiO-66-Br surface with UiO-66-Br as initiator and 10-phenylphenthiazine (PTH) as catalyst, and UiO-66 based hybrid materials (UiO-66-g-PMMA and UiO-66-g-PMMA-co-Eu complex) were obtained. The materials were characterized by fourier infrared spectroscopy (FT-IR), X-ray photoelectron spectroscopy (XPS), X-ray powder diffraction (XRD) thermogravimetry analysis (TGA), gel permeation chromatography (GPC), scanning electron microscopy (SEM) and so on. The results showed that the MOFs material UiO-66-Br with octahedral crystal structure was successfully synthesized, the PMMA and Eu complex chains were successfully grafted from the surface of the UiO-66-Br, the polymer grafting rate of UiO-66-g-PMMA reached 3.01 %, and the Eu content of UiO-66-g-PMMA-co-Eu complex reached 11.81 %. Water wettability test indicated that the contact angles of the hybrid materials were 155.4° and 153.3° respectively. The oil-water separation and self-cleaning experiment confirmed that the UiO-66 based hybrid materials had good oil-water separation and self-cleaning properties.
