| Abstract: | The composite polydimethylsiloxane( PDMS) membranes filled with nano-silica were prepared for the separation of ethanol from water. The pervaporation properties of nano-silica filled silicone rubber membranes was studied by contrast with no filled. It showed that the separation factor was higher than the PDMS composite membrane. During the 3 % to 4 % of the concentration of the alcohol the separation and the permeation rate were 16.09 and 75.39 g/m2·h respectively. The influence of filling silica on the mechanical properties of the membrane were also studied, the tensile-strength was 1.828 Mpa which was 5 times than the PDMS composite membrane(0.368 Mpa). |
