Robust Superhydrophobic PDMS@SiO2@UiO66-OSiR Sponge for Efficient Water-in-Oil Emulsion Separation

“…57 The main diffraction peaks of UiO66-OSiR shift to the low angle, suggesting that modification of UiO66-(OH) 2 . 58 The major diffraction peaks of the PDMS@SiO 2 @UiO66-OSiR sponge were in accordance with UiO66-OSiR. In addition, thermogravimetric analysis was performed to investigate the thermal stability of the PDMS@SiO 2 @UiO66-OSiR sponge ranging from 25 to 800 °C.…”

“…Compared with the pristine sponge, the UiO66-(OH) 2 , UiO66-OSiR, and PDMS@SiO 2 @UiO66-OSiR sponge showed sharp diffraction peaks at 2θ = 7.4, 8.5, and 25.7°, which were assigned to UiO66 metal–organic framework materials . The main diffraction peaks of UiO66-OSiR shift to the low angle, suggesting that modification of UiO66-(OH) 2 . The major diffraction peaks of the PDMS@SiO 2 @UiO66-OSiR sponge were in accordance with UiO66-OSiR.…”

“…Furthermore, the as-prepared sponge sustained superhydrophobic stability with a contact angle of 153.9 ± 2.1°( Figure 4c) under ultrasonic treatment for 80 min. With the advantages of strong acid/alkali corrosion resistance and high thermal stability of UiO66 nanoparticles, 58 as well as the excellent stability and corrosion resistance of the PDMS-coated sponge, 54 the PDMS@SiO 2 @UiO66-OSiR sponge could maintain outstanding superhydrophobic stability and durability in various corrosive and complex environments.…”

On membrane-based approaches for rare earths separation and extraction – Recent developments

“…The hybrid materials possessing in their structure supramolecules, e.g. MOFs and carbon-based materials are in the spotlight of the researcher for REEs separation [293]. Tursi and co-workers [294] generated a novel bioMOF-based single-walled carbon nanotube bucky paper (SWCNTBP).…”

Construction and hydrophilic modification of dual-network structured nonwoven/UHMWPE composite membranes for water processing

“…With the shortage of global water resources which is increasingly serious, wastewater treatment has become the main way to recycle and regenerate water resources. [1][2][3][4] Compared with the traditional separation technology, membrane separation technology has been widely used in the eld of wastewater treatment because of its high efficiency, low energy consumption and wide range of applications. [5][6][7][8] Moreover, nonwoven materials have developed rapidly due to their short process, fast production speed, high output and low cost.…”
