Abstract:

A series of ethylene vinyl acetate (EVA)/Mg-Al layered double hydroxide (LDH) nanocomposites membrane with VA containing 40 wt% were prepared by solution blending method and applied on the CO2/N2/O2 gas separation, whereas, LDH nanolayer material was prepared by using co-precipitation method with 12-aminododecanoic acid (12AA) as intercalation agent. X-ray diffraction pattern shows that 12AA was successfully intercalated within LDH. The distance between the nanolayers of LDH was ca. 21.47 ??. Moreover, the X???ray diffraction pattern and transmission electron microscopic indicated that the exfoliated/intercalated structure of LDH was formed within EVA matrix. The performance of gas permeation for the EVA/Mg-Al LDH nanocomposites membrane was measured at constant temperature with constant volume/variable pressure system. The result shows that the selectivity of CO2/N2 was increased to 20 with permeability of CO2 at 119.21 barriers as the nanocomposite membrane contained 1 wt% Mg-Al LDH. The above result attributed from the Mg-Al LDH has been exfoliated within polymer matrix. In addition, the amino group of 12AA has more interaction with CO2 rather than other gas such as N2 and O2. Consequently, the EVA/Mg-Al LDH nanocomposite membranes have higher gas separation performance than neat EVA membrane.
