Influence of Nanoscaled SiO2 Particles on the Pervaporation Performance of PDMS Membranes

Abstract:

In this article, the polydimethylsiloxane (103-PDMS) membranes filled with nanoscaled SiO2 particles were successfully prepared by polydimethylsiloxane (103-silastic) The effects of silica content, feed concentration, and feed temperature on the pervaporation performances of the 103-PDMS membranes were investigated for recovering propylene glycol methyl ether (PGME) from aqueous solution by pervaporation. It was found that adding the nanoscaled silica particles significantly improved the pervaporation performances of the 103-PDMS membranes. In addition, the possible causes were basically investigated by environmental scanning electron microscope (ESEM).
