ABSTRACT
Polymer/nanoparticle mixed matrix membranes (MMMs) is one of the most important topics in gas separation field. In this study, to improve gas separation efficiency, methoxy poly(ethylene glycol) methacrylate (MPEG) was grafted on TiO2 surface and was used for synthesis of poly (methyl methacrylate) (PMMA) MMMs. Gas permeation and separation properties of PMMA/PMPEG-TiO2 MMMs were studied for CO2, CH4, O2, and N2 gases. The results showed that the MMM filled with 5 wt% PMPEG-TiO2 nanoparticle exhibited optimal separation performance with CO2 permeability of 32.48 Barrer and CO2/N2 selectivity of 56.98, which are higher than pure polymer (2.75 Barrer and 36.71).
