Mono-(2,3-Epoxy)Propylether Terminated Polydimethylsiloxane, Asymmetric,10 - 15 cSt

Liu, Siyuan. (2023).

Nano-sized UiO-66-NH2 particles were surface modified by a liquid polymer, mono-(2,3-epoxy)propylether terminated polydimethylsiloxane, and turned into liquid. The polymer is a polydimethylsiloxane with a mono-terminated epoxy group at the end of the chain, so it can react with the amino group on the UiO-66-NH2 ligand. The synthesized transparent porous liquid can be used for methylene blue adsorption
Nano-sized particles (~20 nm) of UiO-66-NH2 were modified with mono-(2,3-epoxy)propylether terminated polydimethylsiloxane, and the modified UiO-66-NH2 was well dispersed in mono-(2,3-epoxy)propylether terminated polydimethylsiloxane. After synthesis, the transparency and porosity of the product were confirmed. The transparency of the product exceeded 80% in the visible light region. Porosity is retained in the product as shown by the higher CO2 adsorption compared to pure MCR-E11. The sedimentation stability of the product was characterized using a LUMiSizer® instrument and the sedimentation velocity was calculated from the time-position resolved transformation curves.
